Yet another film star is making tracks to Fox's resurgent Ally McBeal. Taye Diggs (How Stella Got Her Groove Back) will appear in six episodes beginning in February as a possible love interest for Lisa Nicole Carson. "I heard he was a fan of the show, so I invited him down to the set. He had a blast," Ally producer Pamela Wisne tells USA Today. "Fortunately, it was a day we were filming bar scenes, which are very fun days." In addition to Diggs, Robert Downey Jr. has begun a 10-episode Ally stint and Anne Heche kicks off a three-episode arc in January.
