Land of the giants. I saw it on METV the other night.
The one where they found the giant 38 special.
Man, was that ever stupid.
Glad someone remembers when the SciFi assault hit TV in the 60's. The one-and-only certified biggest stinker? Hard to pick only one, but you can bet Irwin Allen produced it. Land of the Giants, Time Tunnel, Lost in Space, Voyage to the Bottom of the Sea (my personal favorite. It jumped the shark when one of the cast was bitten by a werewolf, When you have a werewolf on the prowl in your submarine, you've got big trouble)
