Corrected entry: In the finishing scene when both Protagonists stand in front of the Cloud Gate in Chicago when the camera moves around behind them and then "flies into" the Cloud Gate, Jake Gyllenhaal's body double is noticeable for he has substantially longer hair.

Correction: That isn't Jake Gyllenhaal's body double. It's Sean Fentress, the man who's life was replaced by Colter Stevens on the train in order to stop the bombing. It would be a mistake to show Colter Stevens' face. Everybody in the film sees him as Sean Fentress, this is demonstrated when Colter goes to the bathroom and sees himself as Sean reflected in the mirror.
