What are the differences between the R-Rated Ending and the Laserdisc Ending by Criterion?
A
Dead Presidents already had problems before the theatrical release with the MPAA and some scenes had to be cut. Unfortunately, there is no available release containing these scenes. The Criterion Laserdisc release offers something in between. The raid on the money transport at the end of the film is found a second time on the LD after the complete main film. This second version contains said scenes. A detailed comparison between both versions with pictures can be found here.
