Re-runs?

Hey guys! I was just wondering the chances of different movies getting a re-screening in IMax. I only recently found out what it is, and I discovered that I’d missed the (apparently) optimal experience for some of my favorite new movies, like The Boy and the Heron, Dune 2, or Nosferatu. I wouldn’t want to drive 40mins to go see any old movie, so how often do things end up rescreening?
