''The Andromeda Strain'' is a 1971 [[ScienceFiction sci-fi]][=/=][[DisasterMovie disaster]] movie based on the [[Literature/TheAndromedaStrain novel of the same name]] by Creator/MichaelCrichton. Directed by Creator/RobertWise, it stars Arthur Hill (Dr. Jeremy Stone), James Olson (Dr. Mark Hall), Kate Reid (Dr. Ruth Leavitt), and David Wayne (Dr. Charles Dutton) and follows the book closely (except for the names of the characters Leavitt and Dutton).

''The Andromeda Strain'' follows a team of scientists who investigate a deadly disease of extraterrestrial origin, which has already wiped out an entire town, save two survivors.

For its time, the film showed impressive special effects. Computers had advanced pen inputs that [[MagicalComputer didn't behave out of character for the era.]]



* AdaptationalAngstUpgrade: The twist near the end that [[spoiler:the SCOOP Project was searching for materials that could be turned into biochemical warfare agents in space]] (and sets off Leavitt and Dutton, who are both somewhat anti-establishment) is given in a backstory InfoDump on the second chapter of the novel, and none of the characters in it are concerned about that detail [[spoiler:so much as the horror of the SCOOP-7 mission having GoneHorriblyRight]].
* AdaptedOut: While it adapts rather reliably the source material, there are a number of removed minor InfoDump talks (including a detail regarding the TitleDrop-Wildfire's request for a codename for the organism to Central Codes specifies it was diagnosed as an infectious strain in the book (hence "Andromeda Strain"), while on the movie it is simply given by Central Codes), one additional patient that is discovered later (a cop that was passing through Piedmont when Andromeda started to spread, was spared immediate death because of his diabetes, and went psychotic on a diner later, shooting everybody and himself-this finally cements the theory that acidosis is harmful to Andromeda), and the detail that the nuclear detonation protocol would have eliminated all air from Level Five several seconds before going off.
* AsciiArt: The computer graphics - hot stuff at the time.
* AvengersAssemble: When Code Wildfire is declared the movie cuts to scenes showing the military coming to collect the four scientists, often interrupting them in mid-work.
* ChekhovsGun:
** Dr. Hall is repeatedly told about Wildfire's nuclear bomb SelfDestructMechanism (which will go off if a disease escapes containment), how he's the only one who can stop it from detonating and how important it is that he be able to get to one of the deactivation terminals quickly. [[spoiler:You can guess what he has to do at the ending of both the movie and novel!]]
** A fighter jet experiences a severe malfunction when it flew past Andromeda -- all of its plastics dissolved, leaving its pilot helpless as the jet crashes. [[spoiler:Andromeda quickly adapts the same form in Level Five and destroys the gaskets keeping the levels uncontaminated, quickly causing a self-destruct mechanism to activate.]]
* CirclingVultures: When the SCOOP team approaches the town of Piedmont they see buzzards circling over the town - a {{Foreshadowing}} of the dead bodies they will find there.
* ContentWarnings: As it says on the original poster (shown above), "Rated G but may be too intense for younger children."
* ConvulsiveSeizures
** After the self-destruct alarm sounds--and [[FromBadToWorse professional decorum deteriorates]]--incidental characters flee, having observing Leavitt's ''grand mal'' seizure. One assumes, "She's got the germ!"
** Less dramatically (but of more significance to the plot) she'd had an absence seizure while monitoring lab results. When a substance is found to inhibit Andromeda's growth, red text flashes on a screen: causing Leavitt to "blank out" for a few seconds. She reports to her colleagues that no cultures were affected.
* CovertGroupWithMundaneFront: The Department of Defense's Wildfire laboratory, a five-story underground facility, is located in the (fictional) town of Flatrock, Nevada, below a U.S.Department of Agriculture research station.
* CrazyPrepared:
-->'''Leavitt''': (Looking at bleak dusty road, turns to Dutton who's driving) You're lost! No one's been down this goat path for years!\\
'''Dutton''': That's how it's supposed to look. We spent $50,000 on this road.\\
'''Leavitt''': (astonished) Putting ''in'' the potholes?\\
'''Dutton''': Covering up the equipment tracks. Heavy equipment leaves a big trail.
* CreatorCameo: When Mark Hall is ordered to stop a surgery he's about to start, one of the doctors in the back of the operating room is Michael Crichton.
* DeadpanSnarker:
** Dr Leavitt often doesn't take a lot of things happening in the Wildfire complex or what is expected seriously. On noticing the crops at the isolated U.S. Departmemt of Agriculture research station which conceals wildfire, she says "Great place to grow pot."
** Later, Leavitt ducks looking at a flashing hazard light on a construction sawhorse, and to hide the real reason for not looking (she has epilepsy) she says, "I never did like red lights. Reminds me of my years in a bordello."
** The old man, Peter Jackson, when the doctors are having a problem with gasket failures and alarms are going off, looks at the video and says to Hall and Stone, "hell of a way to run a hospital!"
* DecontaminationChamber: There is a long sequence in one of these while the scientists are entering Wildfire, done to prevent any outside contaminants from getting inside. (There is a similar long sequence in the book.)
* DramaticallyMissingThePoint: When Dr. Hall is first given the key to prevent the nuclear device from detonating if the computer controlled auto countdown starts, he thinks it would be his job to initiate it.
* ElaborateUndergroundBase: The Wildfire compound-composed of five levels, each level more sterilized than the last, with top-of-the-line ([[TechnologyMarchesOn for its time]]) bio-warfare research and computer equipment and a nuclear self-destruct.
* FanserviceExtra: The topless hippie girl who is amongst the Piedmont casualties, and we get a long shot of her upper body on the montage of said casualties being checked by the Wildfire team.
* ForWantOfANail
** A simple piece of paper prevented the notification bell from ringing.
** They only installed 3 self-destruct cancellation stations per level, but they need 5, of which the last two aren't yet finished. [[spoiler: Guess where the only person with the key to prevent self destruct is locked into when the self destruct mechanism activates.]]
** As mentioned before on ConvulsiveSeizures, the Wildfire team would have found a potential cure for Andromeda earlier in the story if Leavitt hadn't been alone in the lab and the computer wasn't set to show the results with massive, blinking red letters.
* GenderFlip: Leavitt was a male (Peter Leavitt) in the book, but was changed to a female in the film.
* GoshdangItToHeck: When Hall asks the old man the baby's name, the following exchange ensues:
-->'''Old Man:''' Give us a butt first.
-->'''Hall:''' We don't allow smoking here.
-->'''Old Man:''' Then go ''fish''.
** Made funny because the old man says it like a PrecisionFStrike.
* HotScientist: Noticeably averted. The lone female is in her fifties and overweight. And, it must be said, one of the most memorable characters in the movie, [[DeadpanSnarker snarking delightfully]] with all her might.
* JustInTime: The countdown is stopped with time to spare.
-->'''Ruth:''' Eight seconds to spare. [[DeadpanSnarker Hardly even exciting.]]
* {{Mockumentary}}: It was marketed as a drama, but the film presents itself as being a dramatisation of real events -- see ThisIsAWorkOfFiction, below.
* {{Pixellation}}: In the men's ultraviolet scan, their privates are blurred.
* ShownTheirWork: An interesting example. When Leavitt has a seizure that's induced by a flashing light, the pattern is actually extremely unlikely to cause a seizure. This wasn't an accident but rather intentionally chosen to prevent triggering them in audiences.
* SpreadingDisasterMapGraphic: An early vector map of North America (think Atari's ''Battle Zone'') calculates the projected spread of the fatal contagion.
* SpySpeak: Dr. Charles Dutton uses Type 3 to enter Project Wildfire.
-->'''Guard:''' Howdy.\\
'''Dutton:''' Howdy Doody.\\
'''Guard:''' You got the time?\\
'''Dutton:''' My watch stopped at 11:46.\\
'''Guard:''' Darn shame.\\
'''Dutton:''' Must be the heat.
* ThePlague (or the threat of it spreading worldwide) sets the whole plot in motion.
* ThisIsAWorkOfFiction: Inverted -- The film starts with this message (interestingly enough, this is one of Crichton's {{Creator Thumbprint}}s):
This film concerns the four-day history of a major American scientific crisis.\\
We received the generous help of many people attached to Project Scoop at Vandenberg Air Force Base and the Wildfire Laboratory in Flatrock, Nevada. They encouraged us to tell the story accurately and in detail. \\
The documents presented here are soon to be made public. They do not in any way jeopardize the national security.
* ThisIsNoTimeForKnitting: In the opening, the pair in biohazard suits are investigating the corpses littering the town:
-->'''Dr. Mark Hall:''' [Removing the pants of the dead doctor] Have a look at his buttocks.
-->'''Dr. Jeremy Stone:''' That's NOT funny.
-->'''Dr. Mark Hall:''' Not meant to be! Normally, blood in a dead person goes to the lowest points. There should be marks of lividity, right? Do you see any purplish marks on his butt?
-->'''Dr. Jeremy Stone:''' No...
* TrackingDevice: Didn't exist in 1971 when the movie was made, but the four scientists can be tracked by the electronic diagram, anywhere in the Wildfire complex. Today, you could do it with an RFID chip embedded in their clothing.
* TypesetInTheFuture: The Eurostyle Bold Extended font (or near equivalent) is used for a lot of wall signage in the Wildfire labs.
* YouCanSeeThatRight: Ruth to Dr. Stone while they're examining the green stain on the meteorite.
