Trivia

Actor John Hoyt (who plays Sidney Stanton in this film) would go on to play the role of the ships doctor in the original pilot episode of Star Trek (1966). The pilot was originally filmed in 1964 but rejected and eventually recast although much of the footage, including the scenes with Hoyt, was reused in the two part story 'The Menagerie' which aired in the first season.

Quotes

[first lines]
Narrator: [spoken over a shot of outer space] Needles in a heavenly haystack. There are more stars in the heavens than there are human beings on Earth. Through telescopes men of science constantly search the infinitesimal corners of our solar system seeking new discoveries, hoping to better understand the laws of the Universe.

The Sky Is Falling!
14 December 2001 | by Bucs1960See all my reviews

Loved this movie!......remember, this was 1951 so don't expect the computer generated special effects that we enjoy today. The roller coaster rocket ship take-off is like something from a comic book but, again, remember when this was made.....who knew about rockets to outer space? Richard Derr, whoever he was, is OK in the lead but seems a little bit laid back for someone who knows the world is going to end with a bang. In fact, most of the cast, seems rather off-hand until the very end when the chips are down and decisions are being made as to who lives and who gets to stay for the big one. There are a lot of familar faces (except for Derr) in this movie although they are mostly second leads and not "stars". Look for some walk-ons from actors on their way down and on their way up......John Ridgely who was a staple in WWII films, Kirk Alyn, Superman from the old serials, and Stuart Whitman who would go on to play some decent roles in the 60's and 70's. This film may not be "Independence Day", but it is the best of the early doomsday/futuristic movies of the time.
