Fans of the Farrelly brothers have come to expect a certain level of outrageousness in their films, whether it’s Ben Stiller’s zipper issue in “There’s Something About Mary” or that heavyset fellow who defecates in a sand trap in “Hall Pass.” But all bets are off in “Movie 43,” a series of loosely related shorts produced and partially directed by Peter Farrelly (Bobby Farrelly was not involved in this project). The film, which opens today, has a dozen different writers and directors, and a cast that includes the likes of Hugh Jackman, Halle Berry, Emma Stone, Gerard Butler, Kate Winslet, and Elizabeth Banks. “Movie 43” is also rated R for reasons that, depending on your taste in comedy, will either amuse or appall. We reached Peter Farrelly by phone in Los Angeles.
