'Ally McBeal' Gil Bellows, who played Ally's longtime love interest Billy Thomas on the David E. Kelley show, had announced he was leaving earlier in the third season but few saw the March 27, 2000, episode coming when Billy reveals he has a brain tumor and then drops dead in the middle of a trial during his closing arguments. When the show came to a close in 2002, Ally comes face-to-face with the ghost of Billy as she prepares to move from Boston to New York for the sake of her daughter. Better off gone: Billy and Ally's long past was one of the main arcs in the show's first season and Bellows' premature departure certainly didn't help the show as it limped through five uneven seasons. Bellows "cheated" death and returned to the show as a "ghost" multiple times, including the series finale. But unless you only play that card once, the "ghost" angle is so overdone. -- Kate Stanhope, LATimes.com George Lange / Fox Broadcasting Co.
