Crescendo (1970)

Crescendo (1970) is a classic film by Alan Gibson about an American woman named Susan Roberts who travels to southern France to do thesis research. Her thesis is about a French composer named Henry Ryman who recently died and she winds up staying with his relatives as she does her research, but they are a lot stranger than she could have anticipated. There is one character, in particular, George, who is Henry's son. George suffered from an accident six years prior and is now in a wheelchair. Susan and George get to know each other and Susan learns that she looks a lot like George's ex-girlfriend who left him after his accident. She learns more about him and the family and learns that there are some secrets that they would rather keep hidden. She also learns that her coming there and staying with them was not as innocent as she initially thought. James Olson plays George and we see his ass when he stands up and starts making out with a lucky woman. A man bursts in and shoots the couple, but not before giving us an ample amount of ass.
