Alligator (1980) runs 1h 31m, directed by Lewis Teague. It is one of 3,647 films in the 100 Minute Movies catalog — every one rated 3.0 or higher by Letterboxd members and short enough to finish in an evening.

A baby alligator is flushed down a toilet and survives by eating discarded lab animals that have been injected with growth hormones. The now gigantic animal escapes the city sewers and goes on a rampage, pursued by a cop and a big-game hunter.
