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

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.

Stiller manages his movie nicely so that all actors get their share of the comic spotlight. Seldom does an ensemble comedy not contain a single weak character or performance as does this one.

Like a dinner whose hors d'oeuvres are far more satisfying and well-composed than the slightly warmed-over main course. Among them are the inspired mock movie trailers and the fake ad that precede "Thunder's" opening credits.
