It’s taken over four weeks happen, but The Dark Knight has finally been toppled from its perch atop the box office rankings. Of course, its fall wasn’t too great, dropping only to number two, but its successor Tropic Thunder is surely pleased with itself right now.

With an estimated weekend gross of $26 million, Tropic Thunder opened on top this week, probably thanks in part to Robert Downey Jr‘s involvement and subsequent press hype. The rejuvenated and forgiven actor is definitely keeping his name out there with his comments last week about The Dark Knight.

Nevertheless, given all that, TDK only finished less than $10 million behind Tropic Thunder with $16.7 million, and just over a million ahead of Star Wars: The Clone Wars ($15.5 million), which has suffered poorly from bad reviews. Though, one look through my review points to a complete bewilderment on my part as to why those reviews are so harsh.

The number four spot went to another new offering, the Kiefer Sutherland horror film Mirrors, which raked in $11 million. Last week’s Seth Rogen comedy, Pineapple Express, came in fifth this time with $10 million.

Looking at the upcoming movies at IMDB, I can’t tell you much about any of the newcomers. Whether that is because I am just ignorant of them, or because they are truly not worthy of mention, we’ll find out as the weeks roll by. But the big movies seem to have come and gone this summer.

Of course, I do look forward to next week to see what another week does for Tropic Thunder, TDK, and The Clone Wars.

As always, thanks to Box Office Mojo for estimated takings.
