Indiana Jones is back in theaters this week as 'Raiders of the Lost Ark' returns for a limited IMAX engagement. Then next week, 'The Complete Indiana Jones Adventures' brings Indiana Jones and his movies (including 'Raiders of the Lost Ark,' 'Temple of Doom' and 'The Last Crusade) to Blu-ray.

To help celebrate, we're looking back on perhaps Indiana Jones' finest adventure - 'Raiders of the Lost Ark' - in a way that you maybe haven't seen before. In this gallery of rare, behind-the-scenes photos, you can get a glimpse of Harrison Ford preparing himself for a scene, Steven Spielberg setting up a shot and even a look at things that didn't make it into the movie.

Below is a gallery of rare behind-the-scenes photos from 'Raiders of the Lost Ark.' Thanks to Paramount Pictures, Eric Vespe of Ain't It Cool and TheRaider.net for their help compiling this gallery.
