From Wikipedia..
When Worlds Collide is a 1951 science fiction film based on the 1932 novel co-written by Philip Gordon Wylie and Edwin Balmer. The movie was filmed in Technicolor, directed by Rudolph Maté and was the winner of 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 Conquest of Space made it impossible.
