Continuity: The 3 main characters are having dinner with Anne Bancroft. You can see Jenna Elfman's dark roots. After she and Ben Stiller go home the roots are light. Did she stop to get her hair touched-up on the way home?

Continuity: In the scene in the karaoke shop, watch the light through the window. Sometimes it's daylight outside, sometimes it's dark.

Continuity: Near the start of the film when Jenna Elfman is talking to Ben Stiller in the airport she asks him 'So, what's happening in your life, I wanna know everything' Ben Stiller is mouthing the lines at the same time.

Continuity: In the beginning scene where Brian is telling his sad story to the bartender at the bar, he pulls out a picture of him, Jacob, and Anna. Then the movie progresses to a sequence of their childhood, and then focuses back in on the picture. The two photos are different. One is a close up of the three kids' heads; the other is taken from much farther away.

Revealing: In the shot where Ben Stiller and Jenna Elfman are in the hallway kissing goodbye, it's obvious that Ben Stiller is standing on something to make him the same height as Jenna Elfman, who is much taller than him in real life.

Continuity: In the next scene between the rabbi and priest on the temple's steps, watch the bad edit cuts back and forth between them (when one's talking, and shot from behind his head you can see his lips are not moving).

Other: When Brian and Jake are sitting against the fence just after being beaten at basketball, Jake asks why Anna called Brian and not him. Brian yells "What are you, in the eighth grade still? Fynn before Shram." When he says "Fynn" which is his surname, he points at Jake, and when he says "Shram," Jake's surname, he points at himself.

Continuity: The two men are talking on the street while waiting to cross the street. Watch the kids around them. The two girls on the left bottom look right at the camera. Another girl towards the mid-right, is just mumbling out words. If you look at her lips, you can tell that those are not words.

Continuity: In the scene where Anna is over at Jake's and Brian is coming up the stairs to go to the Karaoke place with Jake, you notice it's light outside. When they get to the Karaoke place it's dark.

Continuity: When Edward Norton shows the photo of himself, Jake and Anna as kids to the guy at the bar, he holds it with one hand in the wide shots (using his other hand to point at it), but with two hands in the close-up shot.

Continuity: In the scene when the priest goes to Elfman's apartment, watch for the fishpole microphone to drop down into the scene.

Continuity: Watch the scene with Ben Stiller and Jenna Elfman after Ben's mum (Anne Bancroft) figures out their relationship. Keep an eye on the Venetian blinds in the background. They begin crooked but somehow straighten themselves out midway through the scene.

Continuity: At the end when Ben Stiller is about to talk to the audience about not being honest the clock is first 10 past 7, 15 seconds later it is a quarter to 8.

Continuity: In the scene where the priest is going over to Jakob's apartment its morning and he says to Jakob we have to go the karaoke place closes in 20mins.  How can that be when it takes time to get there and they were there for a fair amount of time?
