Continuity mistake: Bill Murray has fewer balloons when he enters the bank than when he's outside.
Continuity mistake: When the hostage gives Grimm the watch, a second later he's already wearing it despite never putting it on.
Continuity mistake: After the bank robbery, Bill Murry is robbed, and the robber takes his wallet, which contains 4 one dollar bills. As the robber walks away, we get a glimpse of Bill's shirt, which is not tucked in and we can see money strapped to his body. But a bit later, we again see Bill's shirt, and this time his shirt is tucked in back and front - there is no money to be seen, and Bill never tucked his shirt in.
