143 - The Big Bird Cage (1972)

Pam Grier finally makes her Grindbin debut, and we get the return of one of the greatest exploitation movie directors of all time, Jack Hill (Switchblade Sisters). Directly after making his first women in prison film (the Big Doll House), Jack Hill returns with The Big Bird Cage, which is one of the oddest takes in the women in prison genre we've seen yet.
