Ender's Game is scheduled to arrive in 2D and 3D on March 25, 2013.
To be honest, I'm not normally a very big fan of 3D movies. I'd much rather watch a movie in full color without the random scenes that seem to only exist to present an opportunity for something to obnoxiously jump out at your face.
That being said, Martin Scorsese's Hugo was an exception. The 3D effects were delicate, well-done, and added to the atmosphere of the film. I'm hoping that if they've chosen to go the three-dimensional route with Ender's Game, which I find very likely, they employ this same subtle sort of 3D.
The Battle Room, guys. In 3D. I don't know if my heart could handle it.
