San Francisco Chronicle by Peter Hartlaub

The movie is laugh-until-your-stomach-hurts hilarious.

Entertainment Weekly by Lisa Schwarzbaum

It's raunchy, outspoken -- and also a smart and agile dissection of art, fame, and the chutzpah of big-budget productions.

If you go see Tropic Thunder this weekend, don't be late. The four fake ads that open the movie are perhaps the apex of its considerable comic invention.

Salon by Stephanie Zacharek

An imperfect work of genius, a satire of Hollywood excess and vanity that dares to tread territory laden with minefields.

Tropic Thunder is the funniest movie of the summer--so funny, in fact, that you start laughing before the film itself has begun.

Rolling Stone by Peter Travers

A knockout of a comedy that keeps you laughing constantly. It's also killer smart, lacing combustible action with explosive gags.

When it's all over, you'll probably have the fondest memories of Robert Downey Jr.'s work. It's been a good year for him, this one coming after "Iron Man." He's back, big time.

If you wait through the credits, you get one last joke in the fine print: The actors shot the whole movie in Hawaii, on the fabulously lush island of Kauai. So while they were shooting a story about indulged prima donnas, they were working themselves in one of the most tourist-friendly spots on Earth. You've gotta smile at that.

From Downey Jr.'s purposely racist embodiment of African-American anachronisms to Black's scatological humor, everything in Tropic Thunder qualifies as satire, not spoof. It's an important distinction. Pauline Kael once noted that "unlike satire, spoofing has no serious objectives; it doesn't attack anything that anyone could take seriously; it has no cleansing power."

Maybe Stiller just seems stilted because he's the only one here who isn't playing to the rafters.
