After watching the History Channel episode, I had to go check out the movie.
While the movie was good, the History Channel show was actually more revealing and a wilder version of what happened than the movie. The only real difference is that the movie is rated R so you get some T&A back in Vegas.
The movie has its humorous moments and yet ends with the morality of finishing a job when you start it and how as a country we cut and run once the battle is won only to lose the war.
Definitely catch the History channel version. If you are still interested after that, catch the movie.
