Continuity mistake: After Mike and Ned fight with lightsabers, when they are in the kitchen Mike's wedding ring moves from his left hand to his right hand and back again, depending on the angle of the shot. (00:21:05)
Visible crew/equipment: Before the start of the last basketball game, when Ned calls out, "Jane!" for the third time in the shot facing him as he tries to pass someone, the actors' green T-mark and three other tape marks - one yellow and two red - are visible on the floor ahead of Ned. (Visible on DVD fullscreen.) (01:29:40)
Continuity mistake: The morning after Mike's party at Ned's house, when Ned finishes vacuuming the rug in the overhead shot the wood floor immediately surrounding the rug is clean, but in the next shot there is a mess right beside the rug, which would have been visible in the previous shot had it been there. (01:20:25)
Continuity mistake: When Mike's talking to his son in the school cafeteria (just before his ridiculing of Stan, the bully) keep an eye on his burger - it's sometimes in his hand, sometimes not, and changes position in the box and tray as well. (00:36:30)
Continuity mistake: When Mike walks into Health class, Mrs. Dell's lectern and stool (upon which the basket of condoms and another basket sit) stand directly in front of the chalkboard, but funny how they are both conveniently gone when Mike knocks Stan to the floor, in front of that chalkboard. (00:44:45 - 00:47:25)
Continuity mistake: When Maggie is crying, at one point Mike puts his arms around her. In the next shot his hand is on his head. (01:09:00)
Visible crew/equipment: After Mike and Alex get home, when Scarlet walks in and asks Alex how the tryouts went, the tape mark is visible on the floor in front of Alex, while he's sitting. (Visible on fullscreen version.)
Answer: I've not seen the movie, but an ex-wife would be closer to her ex-husband than a coach to his old student, no matter how good.
