70MM is still the best format to experience this film and tonight is the last night that most theaters in America will be playing Interstellar. All of the 70MM theatres in my 5 hour radius are showing it for a last time this evening.
I’ve now seen it in 35mm film, 35mm IMAX and 70mm IMAX with hopes to see it in Digital next week. 70 is the only way you should see this movie if you can. Looking at the box office earnings, this film seems like such a sleeper hit and I don’t know why. Flawless movie.
