Miley Cyrus, Tyler Perry, Titans Don't Really Clash

On a box-office weekend of far-ranging missions (and ticket prices), the 3D Clash of the Titans scooped up the most money, an estimated $61.4 million, while Tyler Perry's Why Did I Get Married, Too? ruled as the top-grosser among 2D-only films, with a huge $30.2 million.

The Last Song, Miley Cyrus' first major venture without Hannah Montana, sounded about right: a fourth-place debut, a $16.2 million Friday-Sunday.

Stay tuned from the complete Top 10 standings.

? Clash of the Titans is the third straight 3D movie to top the weekend box office. In fact, in 14 weekends so far this year, a 3D movie has been on top 10 times. The trend is a matter of appeal?and math. 3D ticket prices are simply higher. As your wallet could have told you.

? Titans actually played in slightly more 2D theaters than 3D ones, but it grossed slighlty more at 3D venues than 2D ones, box-office tracker Exhibitor Relations said.

? Titans' debut was big, but not titanic. 300, from the same studio, and sporting the same kind of man-skirts, but without the help of 3D ticket prices, bowed with more than $70 million three years ago.

? Why Did I Get Married, Too? is Perry's second-biggest opener, and his biggest opener without the help of Madea.

? Since opening Wednesday, The Last Song has grossed $25.6 million. All told, that's nowhere near Dear John, to name another Nicholas Sparks-spawned romantic drama, but it's already bigger than Robert Pattinson's Remember Me, to name another star U-turn. Assessed Exhibitor Relations' Jeff Bock in an email: "I'd say that Miley Cyrus' debut?sans her Disney doppelgänger?is right on target as her formidable tween audience follows her into teenage-dom."

? In its second weekend, How to Train Your Dragon ($29.2 million; $92.3 million overall) held well, even as it lost 3D screens, and its No. 1 spot, to Clash of the Titans.

? Despite its tepid start, Hot Tub Time Machine ($8 million; $27.8 million overall) hung in there with a better-than-average second weekend.

? Matt Damon's $100 million or so Green Zone ($1.2 million) is out of the Top 10 after three weekends, and, whoops, only $33.1 million. (Worldwide, the film has grossed a still-not-good $61.2 million, per Box Office Mojo.)

? In its fifth weekend, Johnny Depp's Alice in Wonderland ($8.3 million) broke the $300 million mark.
