Scott saw Avengers Endgame last night and he says that even though the film is three hours long, it moves pretty well and he never checked his watch. If you're a Marvel fan, you'll find it very satisfying. Scott also said that since this was the end of the 22 movie Infinity Saga, there is no end or mid-credits scene. Scott saw it in Dolby Cinema and it was beautiful. The film was shot entirely on IMAX cameras; you don't see that much more. If you want to see it in IMAX, make sure your IMAX theater has laser illuminated IMAX or Dolby.
