Yeah. American Pie: Revealed is one of the most entertaining documentaries I've ever seen on a DVD. It might run three and a half hours long, but it doesn't feel like that at all.
The two Beneath the Crust volumes out there (attached to the CE editions of American Pie and American Pie 2) are both 25 minutes long. All the footage on the two volumes (plus more) is included in the American Pie: Revealed documentary in the American Wedding gift set.
