Revealing mistake: While Suit is in a coma, there's a closeup of the monitor beside his bed showing Suit's vitals, and at the top of the monitor's screen are the words "adult simulating," with the timed "simulating" flashing off and on. There's also a strip of narrow filament tape covering "simulating," but the tape is transparent, so we can still see it flashing. (01:17:25)
Visible crew/equipment: The morning after Jesse loses Boomer, when Molly enters the police station and walks past the office windows, we can see the reflection of the boom operator holding up the boom pole. (01:12:20)
Continuity mistake: In the scene where Haley is sitting in the bathtub full of ice, she is wearing a black sports bra. The shot then switches to some of the girls watching a news report from the Worlds competition. It then switches back to Haley, who is now wearing a gray sports bra.
Visible crew/equipment: When Angier goes to Tesla's laboratory and walks to the gate, on the far right side of the fence a figure can be seen, apparently holding something ahead. It seems to be one of the film crew holding a boom mike upright. (00:09:59)
Other mistake: When Bruce and Mos Def are running through the alley near the beginning, they run past a Chinese man who slams a dumpster lid shut. Once Bruce pulls out his gun to look back, that same man starts running because he gets scared. In the next shot, he continues running, but soon stops as if he thinks filming is over. This is visible right before the camera pans to the right.
