Zack & Miri Make a Porno (2008) - 6 mistakes

Continuity: When Zack is talking to Deacon at the hockey game, there's a water bottle between them. It disappears during the rest of the scene, even if the two characters are not seen drinking.

Factual error: Towards the end when Delaney is showing Zack the footage of him and Miri, we see shots where the camera is pointing up at Zack from the ground. But they only had the one camera at a wide angle, and filmed the scene only one time, so they had no way of getting those shots.

Plot hole: There is a problem with the warehouse being destroyed to the total surprise of the crew. A building of that size that is bound to be destroyed has to be fenced off days before the destruction, so that no homeless people or kids can easily get on the properties. In this case, however, there was not even a warning sign.

Factual error: At the beginning of the movie, Miri pulls over, off of the highway, so that Zack can get the "hot hands" hand warmer out of his pants. Miri pulls over at Ralph's Army and Navy Supply Store parking lot. She pulls over to the right, and did not cross over any traffic, indicating that she pulled over on the same side of the road. Moments later, they pull in to the Monroeville Mall, also pulling in to the right. Geographically, if driving down Rt 22 East, one would come to the mall first. Ralph's is another 1.35 miles down the road.

Continuity: When Miri first puts her name tag on at the reunion, it is on her dress and straight. Cut to the next shot and the tag is further up her dress. Cut again and it is back to its original position.

Continuity: When Miri bangs on Zack's door the second time to wake him up at the start of the film, he throws a hockey stick into the hall and it lands on a rug. The shot cuts to him getting up and then back to the hallway, where the hockey stick is no longer on the rug (and Miri was in the bathroom).
