Spent part of the day watching Moon Over Parador, an old favorite of mine with Richard Dreyfuss as an actor having to impersonate a dead Latin American dictator. Directed by Paul Mazursky, its a very funny film that predates Dave by a few years, another favorite of mine.
Best part for me and the part I relate to most as a frustrated actor, is when he first nails a public performance as the dictator, an acting coup if there ever was one, and then is handed a newspaper right afterwards as he is kvelling about how well he did. He looks at the newspaper and then slams it "They're doing Streetcar at Lincoln Center? Dammit! I would kill to read for Mitch!!"
