Clash of the Titans Set to Rule Box Office

Toplined by Sam Worthington, the remake of the 1981 cult classic opens at 8 tonight in about 3,000 2D and 3D theaters. Starting on Friday, "Titans" will play in roughly 3,700 theaters, with about half showing the action fantasy on at least one 3D screen and the others playing it in 2D only.

That represents about 17% fewer 3D venues than DreamWorks Animation's "How to Train Your Dragon," which Paramount bowed last weekend in 2,178 3D theaters and 4,055 locations overall. But it seems enough to validate a decision by Warners just a couple months ago to convert "Titans" to 3D to exploit the format's surging popularity.
