Revealing mistake: In the scene where Evan wakes up and notices that he has no arms, right when you see the stubs you can see a faint shadow moving next to his head and moving on the headboard. This shadow is the shadow of his hand before it was digitally removed. (00:29:15)
Revealing mistake: Although the film is supposedly set in New York, there is a Canadian speed limit sign in one of the first shots. Across the street which Evan lives on.
Revealing mistake: In the first scene of the film, Evan is writing frantically in a journal and his last words that the camera zooms in on are "Save her". Look closely and you can see that those same words are already indented on the page as indicated by a visible letter "s" and "h" and a period that had already been written on the pad of paper. Obviously they had done some other takes. (00:01:35)
Suggested correction: This isn't necessarily a correction so much as a possible explanation. It's possible that the religious inmate (I think his name was Carlos) just simply didn't see the scars on Evan's hands when he first came to the prison in the timeline where he got the scars or Evan knew to hide them in the scar timeline (due to the fact that it was the sole purpose of him going back) and due to his fanaticism he didn't question him a second time.
Nope, after jamming those things in his hands Evan simply came into the prison with the scars already on his hands and would have never thought of showing the religious guy his powers using that particular moment in the past to convince him, or doing what he did a second time as he already had done it. It doesn't matter if the religious guy didn't see them before, they won't be the object of Evan convincing him. He would have had to try it some other way, each and ever time. That how this time travel works and its definitely a plot hole that it worked as it did, whilst it shouldn't have. Of course, it's a time travel movie and they never make sense.

Additionally, the inmate was looking at Evan's palms when Evan traveled back, and when he returned to the present, the inmate remarked that the stigmata marks came out of nowhere.
