[REQ] Horror/thriller movie, young boy knows secret & forces girl to strip w/it

[jimminy3]

Hi there, first post. I remember seeing a clip from a movie (old) where a young boy knows the secret cause of (his father's?) someones death, and forces his caretaker (decently pretty woman) to strip in order to gain that knowledge. It takes place in a bedroom (70's style?) with the boy in bed or in a chair, and the girl standing and stripping slowly.

The actress is Britt Ekland - "Night Hair Child" or "What the Peeper Saw". I think it was posted here although I can't find it.
