Tom Cruise, Katie Holmes Face Protestors at Tropic Thunder Premiere

Protestors didn't dampen the celebratory mood for Katie Holmes and Tom Cruise at Monday's premiere of Tropic Thunder in Los Angeles.

Holding hands, Holmes — in heels that made her considerably taller than Cruise — and her husband walked the red carpet. After they finished taking pictures, they signed autographs for fans before heading into the theater.

During the last scene of the movie — which features Cruise in a dancing sequence — Holmes clapped loudly and couldn't stop laughing. (Cruise's kids, Connor and Isabella, sat behind them during the screening.)

"Tom Cruise is an absolute revelation in this movie," writer Etan Coen told Usmagazine.com. "People will not believe it. You won't be disappointed."

Despite Cruise's comedic twist, some are slamming the comedy – about a group of actors shooting a big-budget war movie — for depicting a negative portrayal of those with mental handicaps. (Robert Downey Jr. also wears a blackface, a racially-charged, old showbiz convention.)

Across the street, protestors held signs, screaming "Tropic Thunder Colossal Blunder!" and "Ban the Movie!"

"I happen to disagree with them in regards to our film," actor Justin Theroux told Us of the protestors. "It’s a shame that they are out there, and I hope that when it comes out, they will actually see the jokes for what they are — a deep cutting satire of Hollywood and the stars."

Said Jack Black: "Everyone has the right to protest. It’s a free country. Anytime that anyone feels that they are justified in their heart, more power to them.

"I just think that the movie speaks for itself, and it’s amazing. I stand behind it, and I am so proud of this movie," he added. "It’s the best movie ever and my favorite movie of the year. That’s my comment.”
