Cuando los mundos chocan

This is one of the least known sci-fi movies from the 1950s, but it's one of the best of the era. The great thing about this movie is that it concerns the lives of the characters and their personal problems.

The plot is about a group of researchers that after a trip in Africa discover some shocking news, that the star Bellus will collide to Earth, destroying the planet. Soon they begin to build a giant rocket ship that will take a group of survivors in Zyra, a safer planet.

The best part of the movie (for me) was the part of all the cataclysms (mountains crumbling, giant sea waves, the Brooklyn Bridge auto-destroying in pieces), and the music fits with the viewer's emotions. I also liked the chemistry between the two main characters (Richard Derr and Barbara Rush), especially in the night-club scene. And the ending is very superb for a 1951 sci-fi movie!

This is a sci-fi movie that every sci-fi fan must see almost once in their life.
