QUOTE: Evan (Robert DeNiro) and movie producer Jack (Martin Landau) in Mistress (1992):
-- Evan Wright: ' Arty films are making money these days, but you need to appeal to an audience's basic motive for going to a movie .'
-- Jack Roth: ' To be entertained .'
-- Evan Wright: ' No, to be titillated. You go to the movies to be titillated. To see sex .'
