Taxi's success was due to its excellent writing, Burrows's award-winning directing using his innovative four-camera technique, and its largely unknown but talented cast. Danny DeVito's Louie DePalma soon became one of the most despised men on television--possibly the most unredeemable and worthless louse of a character ever to reside on the small screen. Andy Kaufman's foreign mechanic Latka Gravas provided over-the-top comedy within an ensemble emphasizing subtle character humor.
