A 3D test of the film has been ordered with the converted scenes to be screened next week before a decision is made.
With conversions, 2D films are run through a process that turns 2D images into 3D. Most 3D movies, including Avatar, are shot in 3D from the start.
Releasing Titans in 3D would be a dramatic statement about the growth of 3D exhibition, as it would be a second big 3D title set for release the final weekend of March, HV notes.
Warners would need to find an ample number of 3D-equipped theaters for the same weekend that Paramount releases DreamWorks Animation's How to Train Your Dragon and a studio insider on the prospect of securing thousands of 3D screens for Titans, told HV: "No problem."
