The version shown on TBS dubs the excessive use of the word "Shit" to "Shoot" or "Shucks." It also omits the nudity during the scene in Zion about 25 minutes in and the lines "You're fucking dead!" and "I'm gonna fucking kill you!" have the expletives cut out of the scene. Plus some of the car chase was omitted.
The 16mm print of the film (sent to college campuses, etc.) features some scenes in letterboxed widescreen form and some scenes in Academy ratio (i.e. full-frame). In at least one scene, this format revealed more than the directors intended (see goofs).
