Other mistake: Near the end of the movie Dwight Yoakam is holding Jodie Foster's daughter captive as he tries to exit the house. Jodie Foster sneaks up behind him with a sledgehammer and swings it at his head. He turns to face her and the metal end of the hammer catches him firmly in his temple, knocking him down a flight of stairs. A few minutes later he comes up the stairs and tackles Jodie Foster to the ground, seemingly unhurt by the impact of the sledgehammer.
Other mistake: Raoul told Junior he wanted ⅓ of whatever's in the panic room, but Junior told Burnham only the two of them (Junior and Burnham) knew the money was in there.
Suggested correction: Like you said, Raoul stated he wanted 1/3rd of *whatever* is in that room. He doesn't know what's in there, but he would assume it would be valuable.
Other mistake: According to the cops at the door, Meg's husband revealed to them that Meg said "There are three" on the phone before the line was cut off. However, earlier in the film during the call, Meg said "There are three men..." and then the line was cut by Burnham. The husband would have heard the word "men" as well to give to the cops.
Suggested correction: Steven (the husband) was just woken up in the middle of the night to a frantic phone call from his wife. Very possible he did not hear, or simply did not recall hearing that one word.
