Activation Sequence

The Activation Sequence is when something is powered up in a usually visual exposition scene. Lights come on, computer screens come to life, the sounds of processors humming is heard, components begin to glow with power, and the camera generally slides across them with loving attention to each detail. Alternatively, it can be done in the background with Bridge Bunnies or radio chatter calling out various sequences. Typically this is done the first time something is seen, whether it's a new toy for the heroes to play with or some ancient device or location that they manage to awaken after centuries of dormancy or a villain's new superweapon.

The aim of such sequences is usually to create a sense of awe and wonder at what they have created, or what has been discovered if it's something good or beneficial. If not, the activation will create a sense of dread at what its activation portents. One significant part of this trope is that the sequence is progressive and takes time. They can last anywhere from thirty seconds to several minutes depending on the context. Sometimes they can last for an entire act.

They are usually done only once to give the audience the idea. If it is done a second time or more, they tend to be abbreviated versions. If the full sequence is shown repeatedly, it may result in a case of Engaging Chevrons.

Compare Transformation Sequence, which may occasionally overlap with this, and Lock and Load Montage. There's the possibility of the device in question being Unfinished, Untested, Used Anyway.

  • Titan A.E.: Cale Tucker needs to power up the Titan to battle the Drej, made more difficult by the ship's batteries being nearly exhausted. Cale almost single-handedly has to jury-rig the mechanism to absorb and convert the Drej Death Ray as a substitute power source.
  • Rock & Rule has The Villain succeed in wresting away The Chick from her bandmates. The boys are sent packing while Mok begins a "departure sequence" that converts much of his mansion into a blimp, complete with deploying the ribs, inflating the helium sacs and detaching utility couplings. No mere Greyhound bus for this Magnificent Bastard.

  • 2010: The Year We Make Contact has a re-activation sequence as Doctor Chandra brings the HAL 900 computer back online after he was deactivated in 2001: A Space Odyssey, reinserting some of the crystal memory cards, testing HAL's functionality reinserting some more until HAL is operational once again.
  • Alien. The very first scenes in the movie are the starship Nostromo's computer and other electrical equipment coming to life in response to the alien signal.
  • Aliens. When the team is trapped on the surface of the planet, Bishop remotely activates the other Drop Ship aboard the Sulaco and prepares it to come pick them up.
  • Apollo 13: Near the end, as they approach Earth, Ken Mattingly in Houston is in the simulator going through power-up procedures, trying to get enough systems up to run the module through re-entry, while not burning through their remaining power. The one we actually see him go through, obviously, is the one that works as the systems each come back up and monitors come back to life. Later he walks Jack Swigert through the procedure on the Odyssey, which had been shut down following the explosion days before.
  • Assassin's Creed: As Cal is put into the Animus for the first time, the arm is lowered, he's strapped in, DNA sequences are scanned and compared, lights come on and he is finally sent to relive the life of his ancestor, Aguilar de Nerha.
  • Back to the Future: The first scene is Marty arriving at Doc's place where he starts activating...something. He switches on the power, activates all the switches, dials up the driver and the overdrive, causing all the dials to go off-scale high. Then we see that this things he's powering up is a giant speaker, which blows him across the room, and blows itself up, when he tries to play a chord on his guitar.
  • Contact has a long sequence showing The Machine being activated for Ellie's flight. The rings are slowly spun up, the control center keeps checking for updates as to their status, and Ellie tries to inform them how the Machine is behaving with each new phase. They almost call it off, but finally go through with it when they barely make out Ellie's "OK to go" through the storm of interference the things is producing.
  • Crimson Tide shows that it takes eight minutes to fuel a submarine's nuclear missiles. It doesn't show the fuel actually flowing through the pipes, but there are progress reports during a scuffle between the captain and XO on the bridge. It's also mentioned that the Soviet missiles, being much larger ICBMs, need fourteen minutes to fuel up. It was an intel report that the Soviet fuel-up order had been given which motivated the Captain and his loyalists to begin the Alabama's launch protocol.
  • The Fifth Element centers around recovering four Plot Devices and installing them in an ancient temple. It's then necessary to trigger the keystones with their respective Four-Element Ensemble, plus one of the main characters as Element Number Five, to activate the BFG that will neutralize the Eldritch Abomination that threatens the Earth.
  • The James Bond film GoldenEye has an elaborate sequence in which a lake in Cuba is drained to reveal that its entire basin is a satellite dish. Three structures that border the now-dry lake extend to towering heights to deploy the antenna array, with which the anarchists intend to transmit the "fire" command to an EMP satellite. Fortunately, Bond is on hand to screw up the device before the command is relayed.
  • Independence Day: The City Destroyers' main cannon. First, the petal-like doors surrounding it open, bathing the target city in an eerie-calm blue light. As eight pylons approach the central spire, it also unlocks and lowers the firing mechanism, the "Hammer." The pylons begin charging the spire, activating the targeting laser that shines down. Then, the "Hammer" fires an energy pulse which obliterates the target building, and the chain reaction quickly moves outwards to wipe out the target city.
  • Pacific Rim: The first time we see an Jeager in action, it's shown activating the control area in the head, which is then attached to the main body, culminating in the neural drift that connects the two pilots and allows them to control the enormous robot. A variant is seen later as Raleigh and Mako are attempting to establish a drift.
  • The Pink Panther Strikes Again: A villainous version, with Dreyfus' Disintegrator Ray taking a long time to activate before being used in an attempt to destroy England.
  • Space Camp: After hearing Max's wish to go into space, Jinx goes to the NASA main network, which he activates in a scene where the top of his main body lifts up with flashing lights coming out of it, while the computers activate one by one, their lights and screens coming on. He does it a second time later, but since we've already seen in by that point this one only lasts about five seconds as opposed to more than thirty.
  • Spies Like Us has one of these broken up into two parts. There's a scene about 45 seconds long where a drive-in movie theater undergoes a transformation into a facility capable of firing an anti-ICBM beam weapon. A minute or so later there's a 1 minute 20 second long sequence where some satellites are moved into "bounce mode" so they can guide the beam properly.
  • Stargate: When the Stargate is first activated, the activation of the chevrons is specifically shown, and when Daniel figures out the final one we are treated to the glowing water of an active Stargate for the first time.
  • Star Trek:
    • Star Trek: The Motion Picture has the refitted Enterprise leaving spacedock. The spacedock lights go dark, things disconnect and get out of the way, there is bridge chatter to report multiple forms of readiness, and in response to Kirk giving the orders for thrusters, Enterprise lights up and starts to move. All to the tune of the film's theme song.
    • Star Trek II: The Wrath of Khan: After the Reliant is shot to pieces by the Enterprise, Khan, in a final act of spite, begins activating the Genesis Device, a process that involves turning a series of cylinders on a control panel and then pushing them down to reveal the next one which starts a final countdown.
    • Star Trek: Insurrection: The Son'a collector's activation process involves deploying large, sail-like structures then firing a probe into the Baku planet's rings to begin drawing in the metaphasic radiation there. We see it three times, first as a simulation Ru'afo is running, second as another simulation to trick Ru'afo into thinking it's been activated, and finally during the climax as Ru'afo and Picard battle inside the thing as it's deploying.
    • Star Trek: Nemesis: After the Enterprise rams the Scimitar, rendering their weapons inoperable, Shinzon activates the thalaron weapon, a process that takes about seven minutes as the targeting emitters on the wings are moved into position prior to firing.
  • Star Wars: A New Hope has the first Death Star need about twenty seconds from "Commence primary ignition" until it looses its Death Ray upon Alderaan. Curiously, this same Death Star needs more than three minutes to charge up enough to expunge the moon of Yavin.
  • Total Recall (1990). When the alien device is activated there is a prolonged sequence of the long-dormant machinery turning on, interspersed with scenes of the protagonists and Big Bad being blown out onto the surface of Mars.

  • Frequently on Airwolf, given it's about a Cool Helicopter. Always accompanied by it's awesome theme music.
  • Stargate Atlantis: After the expedition arrives on Atlantis for the first time, the city, which had been slumbering, begins reactivating. Unfortunately, this quickly proves to be a problem as Atlantis' power sources have been completely drained, and since they are underwater, the more power they use, the less of the city is able to be kept dry.
  • Star Trek: Enterprise: In "In A Mirror, Darkly", Archer and his away team are required to power-up the TOS-era USS Defiant, complete with a pan round the bridge as all the workstations light up and the familiar TOS sound effects come in one by one.
  • Star Trek: Discovery occasionally features the activation of the spore drive, complete with the Computer Voice announcing "Black Alert". The sequence usually involves retrieving a canister of spores from a wall storage and inserting it into the console, which fills the reaction chamber with the spores. Later on, the tardigrade or Lieutenant Stamets are also shown being injected with interface probes from the device retrieved from the USS Glenn. Oh, and there are two sets of rings around the saucer section of the ship that spin in opposite directions as part of the drive's operation. The jump itself has the ship spin along its longitudinal axis in both directions at the same time, before teleporting away.

  • One of the most iconic examples of this comes from Portal 2, when Chell and Wheatley accidentally reboot GLaDOS. The Scenery Porn/Scenery Gorn, plus the ENORMOUS amounts of Technology Porn, added with the sheer panic in Wheatley's voice as GLaDOS slowly gets up from the ground makes this scene absolutely gorgeous. If you're interested, here it is.
  • Halo:
    • Halo 2: The final battle takes place as Tartarus activates Installation 05. While the Arbiter and Sgt. Johnson try to take him down, 343 Guilty Spark keeps announcing various power-up phases completing in preparation to fire.
    • Halo 3: When Truth activates the Ark, the Control Room terminal begins to rise and change, and the holographic Halo rings down the corridor begin to light up one by one.
  • Kirby: Planet Robobot: The first time Kirby took an Invader Armor, we're treated to a sequence where Kirby is reconfiguring the armor with a mechanical-styled footage, changing the mech in the process to be more operable for Kirby: the titular Robobot Armor. The sequence ends with an explosion in the background.

  • StarCraft I: At the end of the Protoss campaign for Brood War, Artanis and Zeratul are activating the Xel'Naga temple, which comprises of them placing the Uraj and Khalis crystals in some kind of power stream, giant arms emerging from the ground around the temple before they emit a wave of energy that wipes out all the Zerg on the planet.
  • Steel Battalion opens up each mission with a length activation routine for the Vertical Tank's Diegetic Interface that you control with the game's absurd 3-joystick controller. Close the hatch, pull up the view screens, activate the power systems, boot up the operating system, balance the VT, and pull up the weapon readouts. Each generation of VT has its own cockpit and startup sequence; first-gens are all analog controls and 7-segment displays, 2nd gen phase in some digital readouts, and 3rd gen are totally digital with multi-faceted viewscreens.
  • World Of War Craft: During the Demon Hunter campaign, the Illidari prepare to jump the Fel Hammer to a Legion controlled world. As you hit the control panel, fel energy is routed around, then a beam of it it shot up through the center as you make the jump.
