Toby Tyler vs Atomic Submarine
I saw these both on a bizarre double bill when they were first released. I was a kid and was there in the theater with my 8 y/o sister.
She got thru Toby Tyler OK, but midway into Atomic Submarine my sister began screaming and screaming and screaming until a matron (!!) had to come down and take her out into the lobby. Hahahaha......
What a strange combination of films!
