Continuity mistake: When the main characters visit Montreal and with their friends they go out to eat at a diner and he creates a "home" out of 4 toothpicks, 3 sugar cubes and a coaster. As the camera goes back and forth in the conversation, watch the "home" on his plate of pancakes. It falls and appears to be scraped and turned in a different direction on his plate by the end of the conversation.
Continuity mistake: When Lex Luthor has his battle suit on and fighting Superman and Batman, the head and neck piece change dramatically and constantly. Sometimes the piece surrounds his head, leaving plenty of room and sometimes his head sticks out over the piece. And it's not a matter of angles, because in some shots, everything being the same, the side piece remains at ear level and his head is either above or below the head piece.

Continuity mistake: When Joel and Dean sit at the booth to talk, Dean places two beers on the table such that the labels are facing the camera. As they talk and the camera switches back and forth between the two friends, Dean's beer switches orientation showing the label in some shots and not in others, despite the fact that he does not touch the bottle whatsoever. There isn't enough time between shots to allow him to move the bottle or drink any as the bottle remains full.
Continuity mistake: Catherine goes home after sex with Chloe yet she later receives a picture on her phone from Chloe in which she's asleep afterwards. When did she fall asleep?
Suggested correction: There's no indication that she went straight home. Lots of people doze off after sex.

Continuity mistake: When Billy and Bolger are driving down the road after the funeral, they are on a 2-lane road, with nothing but grass and trees on either side. But when the shot changes so they're facing the camera, it's a 4-lane road with a lot more traffic. Then the road becomes much bigger with a median.

Continuity mistake: The location of Mr. Ferguson's body on the rug (while he was apparently in a "mushroom stupor") changed a few times. He started with his head near the lefthand edge of the rug, but was about a yard toward the right edge when Nick was walking past him. A little later, Mr. Ferguson's feet were at the right edge of the rug, then about a foot beyond the rug, but his body was back to the middle with the next camera shift. (01:01:35 - 01:04:23)

Continuity mistake: When Eve pushes Chev down the stairs at the horse track, we can see there are more seats underneath them. But they fall over the side and onto the track (close to the wall). In the next few shots they start to have sex, and when the camera pans out they are in the middle of the horse track without ever getting up.
Continuity mistake: When the family is in a parking lot, the amount of beer in the glass on the car's rooftop keeps changing between shots.
