Day the World Ended (1955) was the fourth film directed by Roger Corman. The events take place after an atomic war has destroyed human civilization.
Some of the acting performances were excellent such as Lori Nelson (also Revenge of the Creature) playing the part of Louise. Her facial expressions convey very well the different emotions her character experiences.
Adele Jergens who plays Ruby gives a standout performance as a burlesque / striptease performer who is a bit past her prime and who is rejected by her companion Tony, the small time hood. She's rough around the edges but her heart is in the right place and we feel for her in her drunken grief.
Richard Denning (Target Earth, The Creature from the Black Lagoon & Creature with the Atom Brain) plays the rational scientist hero effortlessly in this and other films.
Mike Connors (TV's Mannix) is perfect as the ruthless uncaring and completely unsympathetic small - time hood, Tony who is only interested in satisfying his own selfish desires.
Convincing performances are also given by Paul Birch (Beast with a Million Eyes & Not of This Earth) who plays Jim Maddison, the decisive authority figure, as well as by Raymond Hatton, the old timer gold prospector, Pete who seems to have ambled onto the set with his mule fresh from a western movie!
Apart from the good acting performances, the film's main strength lies in its portrayal of the interactions, conflicts and emotions of the characters as they try to survive within the limited confines of their post-atomic world.
The Day The World Ended uses its low-budget to good effect with its limited, confining and almost claustrophobic setting.
