Colleague Paul Feig, of "Freaks And Geeks" fame, explains:
Judd actually has this whole thing they do with side-by-side screenings at two theaters right next door to each other and do a “P” version, which is a polished version, which is the one we think is close to what we want to have be our final cut. And then another one called the “E” version, the extended version, which is the dumping ground for everything we think might work, or we wanted to try, or we’re just curious if it’s gonna work. And out of all of those screenings, you’ll always get about five or 10 new things that you didn’t think were ever gonna work that go through the roof and you plug ’em into the polished one.
