all day: Movies

Everyone (at least everyone in this town) knows how hard it is to get a movie made even when all the stars are on board, all the permits are signed and the financial backing is in place. Imagine making a low-budget movie, guerrilla style, with a major action star . . . without that actor’s knowledge. That’s the scenario in “Bowfinger,” a comic skewering of the movie-making business written by Steve Martin and directed by Frank Oz. Martin plays a wannabe movie producer whose attempts to make a film with Kit Ramsey (Eddie Murphy)--an ego-driven box-office powerhouse--results in comedic chaos. The film also stars Heather Graham as an ambitious ingenue, Christine Baranski as an aging B-movie diva and Robert Downey Jr. as a sleazy studio executive. Murphy also plays Kit’s ultra-nerdy but good-hearted brother, Jiff.

* “Bowfinger,” rated PG-13 for sex-related material and language, opens Friday in general release.

8 pm: Theater/Music
