EXCLUSIVE: Watching the sausage being made when it comes to major studio laughers isn’t pretty. So here’s a very typical example. Ever since shooting began on the threequel in the lucrative franchise, Universal has been trying to figure out how to improve its Little Fockers. At one point, replacing director Paul Weitz with producer-writer John Hamburg was contemplated early on and then rejected after Hamburg visited the set one weekend. That’s because everyone realized what a DGA mess this would result in. Plus, Adam Fogelson had just taken over as chairman and didn’t want to throw the already traumatized studio into a worse funk. So the decision was made to fix the movie in post. For about 4 to 5 weeks now, Weitz, Hamburg, Jay Roach, and Ben Stiller have been going through the footage. The good news is that they just decided that re-shoots aren’t needed. The not-so-good news is that they think a week of pickups with all the principal cast in September is required.
