Continuity: When Claire and Eric are painting together in his apartment, Claire's brush strokes are missing when we see the painting again.
Continuity: When Arkin comes to visit Claire at her group therapy room there's a cut of Arkin talking with the first person that approach him. Then we see a cut of that person talking with Arkin. Followed by a cut back to Arkin responding to that persons answer. During the first cut of Arkin we clearly can see someone in the background walking downstairs. That person walks down the same steps when we see the second cut of Arkin talking.
Miscellaneous: In the Special Thanks credits for the "Making of" featurette on the DVD, Andre Braugher's first name is misspelled Andrea.
Continuity: The painting in the scene when Claire and Eric are in his apartment changes from when Eric first gives Claire the brush to when she first begins to apply paint. It is mainly blue but suddenly has all this white at the bottom and the shape of the blue is very different. Then it changes again when they show them from the left, and then again when they step back from it.
Continuity: Eric sits on the wrong seat in the plane wreck and later describes it as his own. (In the final plane crash scene Eric sits in the outer seat, while in the wreck he sits in the inner and middle seats)
