I've heard of the term "LieMax" where it's to describe people's IMAX theaters that aren't really IMAX.
How do I know if my location isn't a "liemax"?

prologue is only
playing with IMAX prints of Mission: Impossible - Ghost Protocol
in film IMAX theaters. Not digital. To check if your local IMAX theater is film and not digital look for theaters with the code "1570", which means the theater has a 70mm, 15-perf projector.
