Corrected entry: In the cab, Deadpool loads 12 bullets into 1 clip, and the number he fires is then counted out onscreen. But during that sequence he's firing from two different handguns, meaning either he has 12 rounds between 2 clips not 1, or more than 12 rounds.
Corrected entry: When Deadpool falls into the dumpster he has no swords, he left them behind. When he climbs out, they are on his back. They disappear again as he walks down the stairs to his apartment.
Correction: The swords are not on his back when he climbs out, only the sheaths, which is consistent with the rest of the scene.
Corrected entry: When Deadpool falls into the dumpster truck he is face down, but next shot he is face up lying on his back.
Correction: After he lands in the truck there is about four seconds shown of Colossus looking at Deadpool's severed hand. It is easily plausible that Deadpool turned over so he wasn't face down in the garbage whilst he was off-screen.
Corrected entry: When Deadpool stabs a man, in one shot he's on his knees, but in the very next shot he's lying down.
Correction: You know how many people get stabbed in this? You want to be more specific, otherwise this can't be confirmed.
Corrected entry: At the beginning of Deadpool his drawing shows him using swords to kill the bad guy, later when we see him actually drawing the picture, he is using guns.
Corrected entry: When they go to fight Ajax, when Deadpool gets out of the cab he has a Desert Eagle in his holster, then while they are walking up Negasonic says "you forgot your duffle bag" and the Desert Eagle has vanished.
Correction: From the instant Deadpool gets out of the cab he has no Desert Eagle.
Corrected entry: At the mutant lab while Angel Dust is drowning Wade into the bathtub, she does with her right hand twice, then in the next shot with her left.
Correction: It's a montage scene and he's being dunked in the goo multiple times. The first time we also see him on his back so his face goes in last, but when he's pulled out, he's on his stomach and he's facing the goo.
Correction: First, Deadpool is not seen loading the rounds into his magazine (it's a magazine, not a clip). He's only counting. And he says 9-10-11-12, meaning he's counting 4 rounds. You can see the magazine only has 4 rounds in it (the magazine has numbered holes used for counting rounds and you can see "5" is empty). He has 2 guns, 8 rounds in one and 4 in the other.
