Oops! I mean peanuts -- the jars in the grocery store that magically right themselves after spilling on the floor.
OK, you got me here, too. I've heard about the pie but to be honest am not sure I've actually seen the discrepency with my own eyes.
But here's one I have seen with my own eyes, and I've never seen anybody else mention it. During the "happy tussle" after TS2, I see a mule start to walk out from behind a bush, and then what appears to be a man step out and pull the mule back behind the bush. If you're in doubt and want to take a close look without putting in the DVD, check out the scene in "4 Nights in 20 Years":

OMG that is so funny I never noticed that before in the Happy Tussle scene way to the left of frame you can see someone hiding in the bushes. Most likely one of the animal wranglers or a production assistant.
What I noticed about the pie scene was in some takes the pie looked 1/2 eaten and in others it appears almost whole and it changes from shot to shot. This scene must have taken several takes to complete and at some point the pie had to be "refreshed".
Yes indeed another Miss match are the peanuts on the shelf at the A&P. Clearly the bottom jars were fallen and broken in the first sequence. These are pretty bad mistakes and fall squarely in the lap of the script supervisor and Ange lee and the Prop Department.
This is the problem when you are making a film on a tight budget like BBM was. Mistakes are made in all films but are usually corrected and screwed up Miss matched sequences are usually noted by the editors and then re shot later to fix the problem's but here it proves that "no money" means "No fix". Also No Money meant they had to "Cheat" some scenes like the camp sites and sheep positions to the camp site because it was more economical that way. Its a Shame they didn't have enough money and maybe 2 extra weeks of production time to finessed this film better. It could be these very issues that cost BBM its best picture Oscar and not really the gay issue but I assume it was a little of both.
Did you also happen to notice in the scene where Ennis and Alma are going to bed and Ennis has the pajama bottoms on the fly is badly gapping in several shots and the editors have blackened out on the negative the "little guy" trying to be the scene stealer??
What really would have helped on BBM is if they would have paid for a Top End script supervisor the Bitchy Bitch Bitch Bitch kind I have worked with on some films before that REALLY have an eye for the details and somehow sees every speck of dust that is out of place. However sometimes Producers hate this type of supervisor because they see them as being over cautious and costing them money because they are so anal. I think it would seem on a low budget film such as BBM it would pay in the long run to "deal" with such a persons perfectionism. However in defense of the script supervisor in many cases the script supervisor is the directors choice and some directors choose a script person because he/she says nothing and lets the director do what he dam pleases this could be the case here also. Some directors are known for mis matched sequences and as long as they are small don't care, its just part of there style of film making.
