Continuity mistake: While John and Emma are talking on the phone at the prison, Emma smiles and says she loves him. In the shots of John, we can see her reflection and she is not smiling. (01:05:00)
Continuity mistake: In the scene where Murdock is in jail talking with Emma on the phones through the glass, he presses his fingers to hers, against the glass, & the glass shatters. Right when it is shattering & he pulls away, if you look very carefully you can see the reflection of his hand in an additional pane of glass that is still there! The next shot shows no glass as they kiss, but when the original glass breaks, there is still a pane of glass remaining, as evidenced by the reflection of his hand. (01:05:08)
