Grandma's Boy

Continuity mistake: When they have rolled all the weed together, Dante lit the bong with both of his hands on the bong, but in the next shot he is just sitting back on the couch.

Continuity mistake: In the beginning of the movie, right after the boxing match on the Xbox, Alex goes into his kitchen to grab a drink. You can see Kevin Nash and another guy in the background. The other guy picks up a coffee maker and places it into a packing box. In the next shot, Alex asks the two guys what's going on, and in the shot after that, you can see the guy grabbing the same coffee maker from behind the box, and placing it into the box again.

Continuity mistake: When people are entering Grandma's house from the Angry Beaver the DJ can be seen walking up the sidewalk, then when it cuts to Dante he's walking up through the lawn.

Plot hole: Contrary to the realism of developing a video game Alex should have had external files such as character models, stage maps and coding on his laptop which he could have used as evidence that JP stole his game, It would be impossible to keep all of the games files on one disc especially if he wanted to change something in the game because if you want to modify a DVD-RW you have to erase the disc data and reburn it.

Dante: This shit is fucking crazy. I don't know how lion got into the neighborhood. I heard some growlin' and shit. So my roommate and I, we go to check this shit out. I look up in the tree, and there's the fucking king of the jungle! It was staring right at me. I almost shit my fucking pants. So I ran inside and called the 5-0.
