Here's why you should buy the 3D version of Infinity War even if you don't like 3D.

Film Find above the trailer for Avengers: Infinity War but showing the comparison between the regular and IMAX presentations. Turns out, A:IW was shot entirely in digital IMAX so the film I saw yesterday was cropped across the top and bottom, which will account for why, just sometimes, the shots were incredibly busy.

IMAX's YouTube channel has a dozen or so videos celebrating the fact and you might also notice that it's not the first to include IMAX scenes. Most of the recent installments have mixed the two aspect ratios so that IMAX visitors have a slightly more epic experience.

What's less known is that those IMAX versions are available for the home on the 3D releases.  Although the standard 2D releases have the regular versions with cropping were necessary, the 3D disc always contains the IMAX version with the shifting between regular and IMAX shots.  Doctor Strange has about three different ratios.

The list seems to be:

Guardians of the Galaxy
Captain America: Civil War
Doctor Strange
Guardians of the Galaxy Vol. 2
Thor: Ragnarok
Black Panther

Of course, you do need to have a 3D blu-ray player and 3D television to see any of this and they're both being phased out.  But you don't have to watch it in 3D.  On my television at least you can turn off the 3D and watch the film without and although you obviously don't get the scale, you can at least see all of the available visual information.

My guess is the 3D release of A:IW will also contain the IMAX version with the full image - unless they decide that's also going to be the 2D version as well if you want to see the whole film, that's the version you're going to have to purchase.
