I don't remember the titles to a lot of the old B ones. There was one where these giant praying mantises came and terrorized the Southwest...about the same time as the giant terantula was going the same thing. There was Attack of the 50 Foot Man and the sequal, Attack of the 50 Foot Woman (the originals, not the remakes)

HEY, how about Lost in Space? I used to watch that a lot once upon a time.

You're probably thinking of BEGINNING OF THE END, starring Peter Graves.

A really cheesy one from that era was "The Black Scorpion"...about a giant scorpion, naturally....cheesy part was the scorpion pulled a train off the tracks, and as the train sailed by on the screen you could see "Lionel Lines" plainly on the coal car....
