Today, I went to see Christopher Nolan's latest movie, Oppenheimer in IMAX 70mm, which is not only the director's intended format, but also the definitive format of this movie. I am lucky to have seen this print of the movie, but also lucky that my IMAX theater in Providence, RI is one of only thirty IMAX theaters in the world to show this film in this format and on a true IMAX screen.
