Another IMAX PSA (Off-Topic)
This tweet is very misleading:

If you are expecting the awesomeness of the IMAX in Dark Knight / Rises, Interstellar, or Dunkirk, think again. Infinity Wars was not shot on IMAX film, but rather a modified Arri 65 in conjunction with the IMAX corp. You're getting an (at most) 6560x3100 image captured digitally. It's not on film. It's not the 1.43:1 aspect ratio. If you've seen films like the Revenant, you've seen what the camera can do. Plus there's gonna be so much CG anyway, most of the frame probably isn't original photography!
Don't be misled.
