The list of cameos in the upcoming Austin Powers 3: Goldmember (2002) is pretty impressive - Britney, the Osbournes, Quincy Jones and Fred Savage (remember the Wonder Years?). However, the most impressive of the lot has got to be the Cruise-Spielberg-Spacey-Paltrow-DeVito uber-cameo. They all appear in a scene where Austin bursts in on a film set and interrupts Spielberg (playing himself) in the process of making a movie about the groovy superspy. In this film-within-a-film, Tom Cruise stars as Powers, Kevin Spacey as Dr Evil, Danny DeVito as Mini-Me and Gwyneth as the faux Bond girl. That's a hell of a lot of star power for one scene.
