He'll have to hope that he can coast on the goodwill from Thunder for a while: Fox wanted to get Hardy Men into production prior to the writers' strike last fall, but since the script from Simon Kinberg (Mr. & Mrs. Smith) needed another draft, Stiller moved forward with a Night at the Museum sequel (due out May 2009). Fox says it remains committed to the movie. ''I wouldn't have thought of Tom until I heard the idea of him and Ben together as brothers,'' says Carla Hacken, executive vice president of production at Fox 2000. ''It made perfect sense.''

Cruise is also ingratiating himself with the top of Hollywood's food chain. In March, he broke bread with Viacom head honcho and former adversary Sumner Redstone, who has since said that he wouldn't mind if Cruise stars in the rumored fourth installment of Mission: Impossible. Sources also say he dined with Fox chief Tom Rothman and meets every three months with Warner Bros. production president Jeff Robinov. (The studio is trying to lure Cruise and Denzel Washington for The 28th Amendment, a political thriller being developed with director Phillip Noyce.) And with rumors abounding that Paramount could be rebooting Cruise's old franchise for a fourth go-round, there's a sense in Hollywood that the actor may indeed achieve what had come to seem like, well, an impossible mission.
