Well Resident Evil would still count then, wouldn’t it?
How about a favorite of mine, Murder by Death.
An Inspector Calls, a play that was turned into a film does take place over one night ( to fit with the concept of Greek Morality Plays I think). The play followed the structure for definite but they may have altered the structure in the film as I haven’t seen it.
Quentin Tarantino’s segment of Four Rooms would fit the bill. Not only does it take place in less than an hour, It is actually made from only two shots, one of which goes until the last 15 minutes. I can’t say about the other segments, because I only saw the Tarantino version at a friend’s.
The entire movie takes place during the night shift on one New Year’s Eve.
In the middle of the second segment, a character receives a mysterious phone call. In the middle of the third segment, a character makes the mysterious phone call. Does that count as a flashback?
The Dresser takes place over a twenty-four hour period, give or take a few minutes. It starts with the curtain calls for a performance of Othello and ends shortly after the conclusion of King Lear the following night. The pre-show preparations for Lear are done almost entirely in real time.
I only saw Speed once, but IIRC, that started in morning rush hour and ended in the evening rush hour of the same day.
Minor pedant: a little under 24 hours. Some of the talking about Cyrus is done during the day before they set off for the meeting that night. It’s not entirely clear in the cinema release of the film, but the extended version adds a scene of Cleon talking to his girlfriend about the meet before they go that makes it indisputable.
