Movie: The Rocky Horror Picture Show (1975)

Rocky Horror would have been dead in the water without Tim Curry's ridiculous Frank N. Furter, but it helps to have at least one other person on the set of a musical who can sing. And no, Meat Loaf doesn't count. Fortunately, Sarandon, then still at the start of her now-impressive career, proved she had the pipes to cut it from the moment she chimed in on "Dammit, Janet."
