Continuity mistake: At the end of the taxi chase where the final biker is hit by the bus, the bus is shown moving at speed, and easily clears the junction where the taxi halted before you heard tyre squeals to signify it stopping. Yet in the next scene as the crowd gather around the presumably dead biker, the scene is shown happening in the middle of the junction, with the bus stopped almost before it's even entered the junction.
Continuity mistake: At the end of the movie Morgan starts singing "Happy Birthday" to Audrey. While Morgan is singing, Audrey is wearing a "Happy Birthday" tiara. Morgan finishes singing, and Audrey goes to blow out of the candle on her birthday cupcake. The camera then shows Audrey blowing out her candle, but the tiara she was wearing is no longer there and mysteriously has disappeared.
Continuity mistake: As Audrey and Drew struggle with the gun, in the shot behind Morgan, Drew has his arms around Audrey, with the gun up by her chest. Cut to a closer shot and the gun's much lower, below his arms, by Audrey's stomach. (01:40:20)
Continuity mistake: After the gym rescue, Sebastian is explaining what's on the drive and leaning forwards. The angle changes as the door opens, and he's suddenly leaning back in his chair.
Continuity mistake: When they're in the cafe in Vienna, Kate McKinnon's arms are all over the place depending on the angle. First shot from the front she's using a spoon and fork, then from behind her left hand is empty on the table. Cut to front, then back, and suddenly she's leaning on the table with her left arm while eating with her right. Then from the front both hands are suddenly empty and she's leaning forwards with her arms crossed. Side shot and the fork is back in her right hand.
Continuity mistake: Just after escaping from the apartment near the start, after saying they're not going to hide in a Pilates Plus, we see a wide shot of them speeding through an intersection, with empty road behind them. Cuts to inside with the conversation continuing, and there's a car directly behind them.
