One of Columbia's very last old time B&W movie serials.
The best thing about this serial is the title itself. I was not a child of the 50s but rather a child of the 70s so perhaps I have a different take on B&W serials than older viewers do?
Whatever the case, I view Columbia's Batman and Robin serial (1949) as the hands down best serial ever made and am always on the look out for another Columbia serial that might just come close to the quality of B&R (1949). No luck with The Lost Planet (1953).
On the positive side, "Planet" is different to just about every serial I have ever seen. Instead of endless fights it has endless boring people (some in a zombie state) talking about boring things. I wish I could use more educated language than that but right now this serial is getting on my nerves - because I expected something better!
Granted, I could not make it past chapter three and the faded Youtube print I watched looked like it came from under a rock, but I would not bother with this one. If you wish to see an old time B&W movie serial set in outer space I would go with Universal's Buck Rogers (1939) or Republic's Radar Men From The Moon (1952).
