Raiders of the Lost Ark - IMAX
Although "Indiana Jones and the Temple of Doom" takes place before it, as everyone will tell you, "Raiders of the Lost Ark" was the first movie made in the series. The film features Harrison Ford as Dr. Henry "Indiana" Jones, an archeologist who has been sent on a quest to find the Ark of the Covenant, an artifact which contains The 10 Commandments -- the actual tablets smashed by Moses when he came down from Mt. Sinai.
The movie that started it all is getting a special one-week IMAX engagement before the full series releases to Blu-ray.
