First I've heard of it. I'm ok with the 3D if it adds something to the film. Alice in Wonderland was pretty good, but others have kind of sucked.
I can't Thor being one of those films that would benefit...
Maybe just a rumor, then.
I’ve not seen any of the new 3D productions, myself, so I don’t know how “real” the effect is, and whether it adds anything all that impressive to a feature, or not.
If it does, then I’ve got an entire list of old movies I’d like to have reprocessed into 3D, starting with the LOTR.
