Dan in Real Life (2007)

Continuity mistake: The whole time Dan is in the bookstore and outside talking to Marie, he is wearing a blue undershirt. However on his way home from the bookstore, he runs a stop sign. When the cop comes up behind him you can see that his undershirt is now grey. When he gets home and walks through the door, his shirt has gone back to blue. So Dan's shirt changes a few times when everything is supposed to be in the same sequence of time and events.

Moles1982

Continuity mistake: In the scene when the mom is making sandwiches she picks up a piece of meat and puts it on the sandwich in her hand but then when the shot changes she is taking that same piece of meat and putting it on the same sandwich, and you can see that she isn't taking another piece and putting on the sandwich because you can see that all she has on the sandwich in her hand is a piece of lettuce.

Disney-Freak

Visible crew/equipment: When Mitch and his brother are singing at the piano, a close up on Mitch's right ear reveals an ear-piece monitor that isn't there when the shot pans out towards the end of the scene.

Trivia: Dianne Wiest (born 1948), who played Dan Burns' mother, Nora, is only fourteen years older than Steve Carell (born 1962).

Dan Burns: I don't want to go out with the pig... face.

Cara Burns: You are a murderer of love.

Dan Burns: You know that feeling in your heart? When your heart is just pounding, like it's actually outside your ribs. Exposed, vulnerable, but wonderful and awful, and heartsick, and alive, all at the same time?
