The Poseidon Adventure (1972, dir. Ronald Neame)

Survivors of an upturned cruise liner race against time to climb to the bottom of the ship. Earnest and clunky, this early entrant into the 70s disaster movie cycle is nevertheless impressive in its technical credits and its commitment of approach, and in its blending of veteran, current, and emerging onscreen talent. Based on a Paul Gallico novel: a sequel and other adaptations followed.

Here’s the trailer.

Airplane! [AKA Flying High] (1980, dir. Jim Abrahams, Jerry Zucker & David Zucker)

An ex-pilot with PTSD has to take control of a passenger jet when its crew are struck by food poisoning. Still-dazzling deadpan parody of 1970s disaster movies (and Zero Hour before them). Some gags and attitudes have dated, but the film’s commitment to strong jokes per minute astonishes. A weak sequel followed.

Here’s the trailer.

Prom Night (1980, dir. Paul Lynch)

A masked killer stalks teens at their high school prom. Early entrant in the slasher subgenre, this mixes elements of whodunnit and giallo, an escaped psycho, plus a childhood tragedy to be avenged. Some arty moments in its direction; the film spawned four sequels and a remake.
