Continuity mistake: In the car, Ryan says the kidnapper sounds like a "monster" and Sarah explains that he's using a voice-change. During this exchange, Sarah goes from looking forward, to looking sideways at Ryan, then back to looking forward instantly between cuts.
Continuity mistake: The T-shirt max uses to clean the blood of Bastian is COMPLETELY covered in blood... until he unfolds it and sees the picture on it, at which point suddenly about 60% of the blood suddenly vanishes from it. It's still bloody... but nowhere NEAR as blood as it was a few seconds prior. (They obviously switched out the shirts between takes).
Continuity mistake: When Max is trying to clean the blood of Bastian the dog with the T-shirt, the amount of blood on Bastian's fur changes slightly depending on the angle. In the profile angle, there's slightly more blood, and in the over-the-shoulder angle, there's slightly less blood. (Most likely the angles are from different takes where they re-applied the fake blood to the dog and it didn't quite match 100%).
Continuity mistake: When Max first reaches down to Bastian the dog in the office, Bastian has his face pressed to the ground and is licking the blood stain. The scene cuts to a profile angle, and suddenly, Bastian's head is no longer pressed to the ground, and is instead lifted almost all the way up.
Continuity mistake: When Max spits out the squeaky toy at Annie, she goes from facing downwards to facing up at Max between cuts.
Continuity mistake: When Annie is showing Max what she got at the convenience store, at one point she pulls a pocket-knife out of the bag and puts it in her hand. The shot cuts to a different angle, and the pocket knife vanishes.
Continuity mistake: At the end of the chase, Annie and Max are in the car. Annie is driving and Max is in the passenger seat because he was shot. Annie screams "I hate game night!" and the scene cuts to an exterior wideshot of the car driving down the road. If you look closely, you can see in the wideshot that only one person is in the car - a man who is driving. Even though in the previous shot Annie was driving and both she and Max were in the car.
Continuity mistake: When Max and Annie find Brooks in the bar, and Brooks tries to explain that he's a smuggler, pay attention. Brook goes from facing Max to facing Annie instantly between cuts at one point.
Continuity mistake: When Annie is dancing around at the bar, the way the scene is tightly cut makes some minor mistakes with where she is in the room. For example, at one point, she is in front of one kidnapper, but then is immediately in front of the next kidnapper between shots. There's a few other little small moments like this throughout the scene. It's hard to notice because of the tight framing, but it's there.
Continuity mistake: When Ryan and Sarah are looking at the clue card that says "Look in Your Jacket Pocket," pay close attention. In the closeup of the card, there's some stuff right behind it, only inches away. Then it cuts to a wideshot, and you can see that there's nothing right behind it. The only things on the table are about a foot away.
Continuity mistake: When Ron, the actor playing the "FBI Agent," is explaining what happened, watch his hands. They go from down to up between shots at one point.
Continuity mistake: When Max notices Brooks through the doorway at the bar, Annie is sipping Max's drink then starts to set it down. The camera cuts to a different angle, and suddenly she is sipping his drink again and puts it down a second time.
Continuity mistake: When Annie and Max are chatting at the bar, watch Annie's arms. (She is leaning against her hand.) In the shots facing her, her red sweater is sticking out of the sleeve of her jacket. In the shots facing away, her red sweater is NOT sticking out of the sleeve of her jacket.
Continuity mistake: When Ryan shoves the table under the doorknob so Kevin and Michelle can't get out of the obvious, pay attention. In the wideshot, you can see that the table is a good 4-6" under the doorknob. Then it cuts to a closeup, and suddenly the table is only about 1" under the doorknob.
Continuity mistake: When Annie and Max are talking about the first riddle and Annie is googling it on her phone, she goes from looking up at Max to looking down at her phone between cuts at one point.
Continuity mistake: When Max gets punched by the kidnappers when they first break in, watch Annie. Her hands go from down on her knees to up playing with her necklace between cuts.
Continuity mistake: When the actor playing the FBI agent is handing out the folders, and Max sarcastically asks if the FBI wants them to solve the kidnapping, watch Max. He goes from looking at the actor to looking down at the table between cuts.
Continuity mistake: While Brooks is telling the embarrassing story about Max trying to give himself fellatio, he says the line "He couldn't unhook himself!" Instantly between cuts, his hand goes from up in the air to down by his waist.
Continuity mistake: When Kevin and Michelle tease Ryan about "needing the validation of Instagram models, " watch closely. In between shots, Kevin and Michelle are instantly looking in different directions and doing different things. (Ex. Between shots, Kevin goes from facing Ryan to facing down, and Michelle goes from holding her own drink to pouring a different drink for Kevin).
Continuity mistake: When Ryan and his date sneak into Max and Annie's house, Ryan knocks over some plants, spilling dirt all over the counter in front of it. It briefly cuts to Max, and when it cuts back, Ryan has put the plants back upright but almost all the dirt has vanished from the counter. It's totally impossible for him to have cleaned up all the dirt in the mere second-or-two that passed between shots.
