* Doors in ''VideoGame/{{Doom}}'' open upwards, primarily due to limitations of the engine. "Polyobjects" from the version of the engine used in ''VideoGame/{{Hexen}}'' and later source ports can be used to make doors that actually imitate real-world door behavior.

(When the source code was released, a routine for horizontally sliding doors was found to be DummiedOut with the comment "ABANDONED TO THE MISTS OF TIME!!!")

** This is explained in the ''VideoGame/MetroidPrime'' games as being a method of bypassing the door's normal opening mechanism; you're basically lowering a weak shield that's there to keep wildlife (or you in the case of stronger ones) out and the doors are opening automatically (presumably there's a more peaceful manner of opening the doors). The ones that need missiles explicitly have a blast shield (which disappears after being removed the first time) on them for extra security. Some areas of ''VideoGame/SuperMetroid'' have doors which lack the shields and just let your straight through when you approach.

** On the ''Series/StarTrekTheNextGeneration'' episode "The First Duty", the Academy dorms have doorknobs and hinges.
*** Probably to give the cadets more things to polish.

** Parodied in ''VideoGame/{{Fallout 3}}'' in the Mechanist's Lair where the main entrance is a ridiculously complex set of doors that take easily couple of minutes to open entirely. It's also a ShoutOut to ''Series/GetSmart'' and/or ''Series/MysteryScienceTheater3000'', being exactly the same as one of the doors in both those series' famous door sequences.

** The defensive iris used on the titular gate of ''Series/StargateSG1''. Arguably, this can be justified because the alien gate didn't come with a convenient slot to allow sliding a solid metal door over the event horizon. But then they completely forgot to explain where the iris disappears to when open and where the presumably complex mechanism for operating it is. By ''Series/StargateAtlantis'', they just had a more prop-friendly generally-invisible ForceField that prevented invasion via "Unscheduled Off-World Activation."

* Likely inspired by the human eye. The iris is a naturally evolved mechanism for opening and closing, and probably the only biological example of a "door" that doesn't invoke {{Squick}}.

* ''Franchise/{{Halo}}''. Most Covenant and Forerunner doors are like this. Covenant doors beep before they open though. The Flood-overrun High Charity in the third game has sphincter doors similar to ''Prey''.

This trope refers to a particular sci-fi convention of connoting a "futuristic" setting with doors and hatches that open in unusual, hi-tech ways - doors that dilate like an iris, doors that slide up into the ceiling, doors that ''dissolve'' and rematerialise... Apparently, plain old hinges are extinct in the future.

* The doors on the industrial ship in ''Anime/GhostInTheShell: Innocence'' don't make any sense. They consists of four squared panels fixed to two hinges on each side of the doorframe at middle height which are tilted sideways and into the walls. However, it [[RuleOfCool looks quite cool]] when Batou charges through the coridors and every 15 meters one of these opens just a split second before he reaches it.
* Seriously, any SciFi anime (especially pre-2000) has these doors.

* ''Series/DoctorWho'' has far, far too many "dilating doors" to list here, but special mention goes to a door in ''Day of the Daleks'' which curls up toward the ceiling in a slow, sinister fashion. ''The Ark in Space'' also features a sliding door that almost takes the Fourth Doctor's arm off. "I'm rather attached to it," he said.
** And, of course, out of universe the classic series TARDIS interior doors qualified--they were supposed to swing open or closed with the push of a button, but (like many of the show's mechanics) rarely functioned correctly. The new series solved this by doing away with the interior doors entirely.
* In ''Series/{{Firefly}}'', on ''Serenity'', the doors to the crew quarters were these elaborate swinging ladder/door combination things. Quite space-efficient, if a bit easy to lock from the wrong side. (And not wheelchair-accessible, although the guest quarters were.)
** Still quite modest for this trope, since all the doors on the ship are opened by hand. The guest quarters have perfectly ordinary, manual sliding doors, again a matter of saving space.
* In ''Series/MysteryScienceTheater3000'', the main characters are compelled through an elaborate series of variously opening doors and into the screening room.
** Well, Cambot is. The audience never sees the other characters during the door sequence; they might be going into the theater through a side door.
** And this might just be a shout out to the opening and ending sequences of Get Smart!
* The doors to personal quarters on the eponymous ''Series/BabylonFive'' open by rotating clockwise. They have been known to fall on cast members. Others open like modern automatic doors, sliding to either side.
** Those doors are actually quite clever, as they're held up by electrical power when open and are closed by the ArtificialGravity produced when the station rotates, with no need for a motor to close them. In the event of a hull breach or life support failure the doors would slam shut on their own without any active safety system required.

* In ''WesternAnimation/TheLegendOfKorra'', the doors in the police station are a semi-complex pattern of sliding metal slats. Justified, because the main body of the police force are trained [[ExtraOreDinary Metal Benders]], and it's their powers - not mechanisms - that move the doors around. Most of the other doors in the series are traditionally hinged or manually slid doors.
