Interstellar Trailer 4k IMAX or Anamorphic Identification

This is a 4k resolution version of the 2nd trailer for Interstellar. This version has a text overlay that marks when IMAX 70mm film is being used and when Anamorphic 35mm film is being used. Christopher Nolan is well known for shooting over half of The Dark Knight Rises in IMAX, and for Interstellar, he’s shooting even more IMAX footage than in The Dark Knight Rises. This can already be seen in the trailer since about half of the trailer is IMAX 70mm footage. He does cheat in a way because all of the exterior spaceship/space shots will be CGI (unless he actually uses model spaceships) so they will be rendered at a digital equivalent to IMAX 70mm (which means it will fill up the entire 4:3 IMAX screen like the space shots in Star Trek Into Darkness) but are not actually shot on 70mm film.
