Anytime Tom Cruise hits the red carpet, expect an event, but the special guests who joined Tom and Jamie Foxx, Monday, for the standing-room only world premiere of "Collateral," made this night the "main event."

"This is nice, I don't expect it," Cruise said of the overwhelming crowds. But co-star Jamie Foxx did, telling Tom, "I told you this was going to be pandemonium."

Tom told us he'd talked to some of the fans. "They just say, ‘Hey how's it going, you know, how's the premiere?'"

In the movie, Tom plays a cold-blooded killer who hi-jacks Jamie Foxx's taxi to snuff out his hit list in a single night, but in real life, Cruise is a genuine, nice guy. The superstar spent the majority of his time at his premiere signing autographs for fans. "That's what it's all about, that's why he has so many fans," said co-star Jada Pinkett Smith.

Jada jumps into the on-screen thrill ride alongside Jamie and Tom, but she flew solo on the red carpet Monday night without her husband, Will. "He's in Germany working," Jada revealed. "He's got to get that money across the world for ‘I Robot,' you know what I mean? You know the Smith family; we're very blessed to have two high-profile films in the summer, so it's not a bad thing that he's not here."

The Foxx-Cruise chemistry commanded such a crowd, that even Diane Ross showed up. And the Supreme diva revealed, "I think I'm going to get back into things, I don't know, music, movies, all of it."

And to make the premiere a full-blown knockout, we made room for the champ, Muhammad Ali.
