Warner Bros.’ “Clash of the Titans” marched to a triumphant $61.4 million in weekend boxoffice to top domestic rankings and seemingly validate the studio’s move to convert the action fantasy into 3D imagery.

The Sam Worthington starrer boasts $64.1 million in cumulative boxoffice, including Thursday night “pre-shows” in mostly 2D venues. During the weekend, “Titans” played in a total 3,777 theaters, including roughly 1,800 3D locations.

Elsewhere during a robust Easter weekend for moviegoing, Lionsgate bowed “Tyler Perry’s Why Did I Get Married Too?” in second place with $30.2 million, the multihyphenate’s second-biggest film opening ever.

Disney got a two-day jump on the session with Miley Cyrus starrer “The Last Song,” as the romantic drama took in $16.2 million in fourth place during the weekend and $25.6 million since its Wednesday bow; both sums were substantially higher than anticipated.

DreamWorks’ 3D animated feature “How to Train Your Dragon,” dropped a scant 33% from its week-earlier opening to register $29.2 million in third place. The solid sophomore session pushed cumulative boxoffice for “Dragon” to $92.3 million.

Another second-weekend holdover — MGM comedy “Hot Tub Time Machine” — fell a modest 43% to $8 million in sixth place, with a 10-day cume of $27.8 million. One rung higher, Disney’s leggy “Alice in Wonderland” conjured $8.3 million from its fifth frame to push cume for the 3D phenom to a mind-bending $309.8 million.

Collectively, the weekend top 10 rung up $169 million, or 15% more than the comparable session last year, a non-Easter frame, Rentrak said.
