Life of Brian is Python's take on Judea at the time of Christ. Brian is a character who's life parallel's Jesus's.
If you're going to buy this, you probably know about the movie and why it's one of the best movies, let alone best comedy, of all time.
The Special Features though are what set it over the top. It's great to hear the Pythons talk about the process, both the god and the bad about the shoot.
What's great about it: Great Special Features, Deleted Scenes, Commentaries
What's not so great: It would have been nice for the Pythons to have been in the same room for their commentaries
