Since you have nothing better to do for the next two hours and 48 minutes, I'm sure you're going to watch all twelve chapters of Zombies of the Stratosphere, a 1952 Republic movie serial about Martians with a fiendish plan. They want to use a hydrogen bomb to knock Earth out of its orbit so Mars can be the third closest planet to the sun. Hey, laugh if you want but there's at least as much a chance of that as there is of Donald Trump building his wall and forcing Mexico to pay for it.
As serials go, this one's unusually tedious at times. Judd Holdren, who did a lot of things like this, plays the hero…but his best moments are doubled by Dale Van Sickel, a "star" stuntman whose stunting career started in the Marx Brothers movie Duck Soup in 1933 and ended in a crash while he was stunt-driving for the 1976 Disney movie, No Deposit, No Return. The only actor you may recognize in this serial is Leonard Nimoy, who plays one of the scheming Martians. Whatever happened to that guy?
