Continuity mistake: The clock in the hotel initially reads 9:21 and then abruptly changes to 9:20. (00:19:48)
Continuity mistake: When Keen enters Red's Bethesda apartment, the camera pans over pictures on the mantel. Directly left of the picture of a little girl/man on a swing, is a picture of a woman holding hands with 2 children (looks like 1980's, adult woman looks like Keen.) When Keen reaches out to pickup/view the swing picture, the woman/children picture is no longer there and a really old family photo is in its place. (00:21:25)
