When Worlds Collide is a 1951 science fiction film based on the 1932 novel co-written by Philip Gordon Wylie and Edwin Balmer. The film was the 1951 Academy Award for special effects.
Producer George Pál considered making a sequel based on the novel After Worlds Collide, but the box office failure of his 1955 movie titled Conquest of Space made it impossible.
The 1951 movie still speaks to us today. It could be seen as presaging our current concerns about climate refugees in a future world beset by runaway global warming....\
Rent the DVD if you have chance. It's a great movie. 1951. Who knew?
