Even though my local theater is 3D, they're not showing it until the 16th.
I'm presuming you are in the U.S. or Canada? Only 3D IMAX
theaters are showing it tomorrow. If you don't have an IMAX theater, you have to wait for the 16th.
Gotcha. The fact that they've been saying Imax/3D (with the slash) made me think it was an either/or scenario. Guess not. C'est la vie.
