70's movie help

[Kevin]

I saw a movie at the drive in & all I can remember is the ending. A girl was kidnapped & raped, in the end she is buried alive but has a tube that goes down to her mouth, a kid is feeding her M&M's.

The pre-teen Rick James and his first crush.

An Olsen twin gets treatment for anorexia.
