Continuity mistake: When Ned and Mike stop for the "glorified midget wrangler", Glenn's right hand goes to his pants' pocket in the shot facing the Lamborghini, but next shot his right arm is extended for the crossing children. The proximity and position of the kids to one another also changes abruptly between shots. (01:21:25)
Continuity mistake: After Ned and Mike arrive in the courtroom, the judge's nameplate moves from being to the right of the gavel, to being directly in front of it, then back again. (01:22:45)
Continuity mistake: When Ned and Mike encounter the street guard, whilst in the yellow car rushing to the court, the rear-view mirror changes position. (01:25:45)
Continuity mistake: In the courtroom, when Mike finishes "reading" the letter to Scarlet he drops it on the case file box, with its black extendable handle retracted below the bar (wood rail), but when Scarlett picks up the paper the extendable handle is pulled up well above the bar. (Visible on DVD fullscreen.) (01:25:50)
Continuity mistake: At court, after "Mark" reads the supposed letter from Mike, he drops the paper onto the box. When Scarlet picks it up and sees that it is merely directions to the courthouse, its writing differs. The direction of the folds in the paper also change from when Scarlet picks it up and the next close-up. (01:25:50)
Continuity mistake: Near the end, when Mike is warming up in the gym, just as Coach Murphy says, "Hey, Gold," as he's walking in there is one basketball on the top tier of the rack (the last ball Mike takes is from the bottom tier), but when Coach Murphy says, "Got a little inside info...," the top tier is empty. (01:28:05)
Continuity mistake: Before the start of the last basketball game, when Ned (wearing a "cloak of invisibility") calls out to Jane, the people surrounding the seated principal change depending on the angle of the shot. For example, in the shot facing Jane there is guy in a green hoodie, wearing a bandana on his head, that disappears in the side shot. (01:29:35)
Continuity mistake: When Maggie is crying about being dumped, her makeup changes from the time Mike first came by her, where it was purple, to the end where it is black.
Continuity mistake: When Ned calls off the Hummer it is immediately in the street behind the Principal, but was completely absent in every shot before that as you can see the street behind her it wasn't there.
Continuity mistake: Scar and Naomi arrive home from happy hour, where Mark is playing 1 on 1 basketball in the driveway. As Naomi exits the driver's side, a small piece of paper falls out onto the floor. In the next shot, it's gone.
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.
