Mutiny In Outer Space (1965)
I had not seen this film in decades. Wow -- it is really bad. A mishmash of sets, bad special effects, really bad dialogue...you get the idea. This one is so bad that I remember seeing it on television on a "Dialing for Dollars" program in the late 60's - early 70's (which means that it didn't survive for long after being released). BONUS: It also features Harold Lloyd Jr. in his final film role. Check it out!

Yes, this would be a good riff - when I saw this post my eyes went over it rather quickly and I somehow read the word 'mismash' 'Amish!' Ha ha! I thought, "Amish in space?" :D
