One good turn deserves another. In return for the song 'Someday,' which was recorded by the Black Eyed Peas and appears in Tom Cruise's upcoming movie 'Knight & Day,' the actor promised to appear in a video by the Peas on 'Good Morning America' (weekdays, 7AM ET on ABC).

"It started here. You started it," Cruise said, crediting George Stephanopoulos for the idea. "You gave me the opening." No doubt that Cruise agrees to the task knowing full well that he can draw upon moves he displayed in both 'Risky Business' and 'Tropic Thunder.'
