Continuity mistake: In the scene where young Jonesy, Beaver, Duddits, Henry and Pete are trying to find Josie they all place their hands on Duddit's shoulders and do the "psychic link" thing. Henry and Pete have tears on their faces, which they wipe away pretty quickly, then Duddits turns to Pete and he still has tears on his face.
Continuity mistake: This is in the scene when all four guys are eating dinner at the table at Hole in the Wall. When all the guys are discussing the memory warehouse and Beaver doesn't remember what it is, he says, "What's the memory warehouse?" As he says this, he puts the beer bottle up to his lips and is drinking while Pete says, "You don't remember the memory warehouse?" Beaver is taking a long sip of beer. In the next shot, Beaver's hands are folded on the table, with no beer bottle near him. There is no shot or any way in which he puts the bottle down.
