There is no easy answer as to why you should see a movie at an IMAX movie theater. I’m usually suspect to IMAX movies because most movies shown in IMAX were not shot using IMAX cameras. So the movie you are watching in an IMAX theater is not a true IMAX movie, just a print of the film big enough to fit the screen.
Christopher Nolan is a director who has the pull in Hollywood to make a true IMAX film. I use the world film because almost every movie theater has converted to digital, so it’s rare to see an actual movie on print. Nolan’s latest movie, Interstellar, was filmed using anamorphic 35 mm and IMAX 70 mm film, so watching it on an IMAX screen will be that epic movie experience that IMAX was always intended for.
If you are someone who is still going to watch Interstellar on a regular screen, be sure to watch this video of AutoNation IMAX Theater Chief Projectionist, Armando Mena, break down what it takes to put Interstellar on an IMAX screen. I think it will help change your mind.
