There was probably one in Friday as well (it said "the door contracted"). Heinlein's Beyond This Horizon had a dilating door. The Guns of Pluto by Allen Steele opens with an airlock's "sphincter door" irising open to admit our hero, making it look like Captain Future has been used for an Ass Shove.Presumably this was either a matter of personal preference on the owner's part or because the filmmakers couldn't get a fancier visual effect to look right. In particular, the windows stand out, as they are not made of a solid substance, but instead seem to be Some Kind of Force Field, marking a pretty stark contrast with the doors. Even stranger when compared with the Ascetic Aesthetic design of the rest of the house. This, of course, is taking place in the entirely virtual world where Cool, but Inefficient is king. The interior of Flynn's house in the Grid has obviously visible hinges and door knobs on all of the doors, such that they wouldn't be out of place in a regular modern house.

Whereas the Star Trek universe does other things (see below), the Starfleet facility on Delta Vega has a normal exterior door with a panic bar.

A crewman gets crushed when his arm is caught as he tries to dive through the Dilating Door as it closes.

Ordinary hatches slide upward or sideways. This makes sense assuming that their intended purpose is to regulate air flow through the ship and not to be pressure-tight in case of a hull breech.
