(1957, Kenneth Tobey, Faith Domergue)

“I remember on TV when I was a little tyke, 'It Came From Beneath The Sea', featuring a half-mile(?) long octopus that took over San Francisco , until it got 'shot'. Of course the more exciting part was earlier in the film when I noticed the back/right side view of a postwar 1949 Fageol trolley Twin Coach bus smiling at me!!! Now that made my day!…. Even though the octopus got shot!” (thanks for the memory Jerry Fretto)
Incidentally, the octopus only had six legs - two were removed due to budgetary constraints……
