By the way, when I was watching it in the cinema, I took off my glasses uncomfortably at the beginning, and then I thought about it and didn’t reconcile the dozens of RMB spent on 3D before putting them on again.
The following is the original English FAQ:
Is the entire film in 3-D?
--No, it is not, but that is due to the filmmaker's wishes. The "real world" footage is presented in 2-D, and the "Electronic world" footage is presented in 3-D, as per the filmmaker's intentions. A disclaimer clarifies this before the opening credits in the 3-D versions of the film and advises that the audience put on their 3-D glasses right then and there due to the Disney logo and the opening credits being presented in 3-D.
is the explanation on IMDB, it is official
