After a month-long, record-breaking run at the top of the box office, "The Dark Knight" has finally met his match. And in a bit of geeky irony, "Iron Man" had a hand in his defeat.

"Tropic Thunder", the outrageously offensive (not to mention downright hysterical) comedy directed by and starring Ben Stiller and co-starring Robert Downey Jr. and Jack Black, earned $26 million in its debut weekend to take the top spot. Its five-day total (it opened on Wed.) stands at $37M, a surprisingly pedestrian number for a mega-hyped comedy that's had overwhelmingly positive reviews. Frankly, I'm shocked 'Tropic' didn't open bigger. Maybe word of mouth will sustain it.

TDK earned $16.8M for a mindblowing $471M total, leapfrogging "Star Wars" to become the second-highest earning film of all time, behind only "Titanic."

Speaking of George Lucas' cosmic cash cow, the animated "Star Wars: The Clone Wars" debuted in third with $15.5M. Fourth place went to Kiefer Sutherland's scary movie "Mirrors" (check out our interview with Kiefer here.)

Bringing up the Top Five rear was "Pineapple Express" with $10M, a 57% drop from its premiere week. Its total now stands at $62.9M.

Meanwhile, Woody Allen's "Vicky Cristina Barcelona", buoyed by strong reviews (like ours, which you can see here) and big name actors like Scarlett Johansson, Javier Bardem and Penelope Cruz, earned a robust $3.7M on 692 screens. The $5,361 per-screen average was the 2nd-highest in the Top 10 behind "Tropic Thunder."

That bodes well for Woody to score his first hit since 2005's "Match Point."
