"When we shot Awakenings, there's a scene where Robert De Niro is frozen in a catatonic state, and a cockroach is supposed to cross the desk. But Bob doesn't like cockroaches very much, and he kept jumping up. So we had to do it a few times. Robin was offscreen all this time pretending to be the voice of the cockroach. He'd yell out things like 'I was up for a part in the Reaid commercial!' which would make Bobby laugh, and then we'd have to wait until Bobby's face was less red from laughing, because he's supposed to be sick."
-Penny Marshall, Actor/Director
