Bob Zmuda ("ZMOO-da")is the co-executive producer of the new film "Man on the Moon" about the late comic Andy Kaufman. Zmuda was also Kaufman's writer, co-conspirator, and close friend. In the 1970s Kaufman was best known for his portrayal of the sweet-natured foreign-born Latka on the TV sitcom "Taxi." On stage he took on mind-bending personas like an obnoxious master of ceremonies, or a wrestler who fought women and challenged them on stage, or an Elvis impersonator. Often he left his audience perplexed as to whether or not he was for real.
