When Worlds Collide?
Correct
Your first picture had me baffled because it was in B&W. I thought at first, the actress on the right, was Dana Wynter, but the only B&W Sci-Fi film she was in, in the fifties, was
Invasion of the Body Snatchers. But there was no spaceship in that film. Once you put up the color image, I went back to the first image, and realized it was Barbara Rush.
BTW, anyone interested in doing a monthly marathon of Science Fiction & Fantasy films in September?
