Continuity mistake: In the parking lot in front of the company he just left, Dan Trunkman is talking with Timothy McWinters and Mike Pancake. Once Mike tells him the reason why he's not working at Footlocker anymore, Dan asks him "Do you work hard?" In this part of the scene as the editing switches back and forth between two main camera angles Tom Wilkinson has either his arms relaxed down his sides, or in front of his belly. (00:04:15)
Other mistake: The day before the business trip, Vince Vaughn enters his son's room. They have an awkward chat about masturbation and when he leaves, his son checks out of the bad things that bullies with even worse photoshop skills post on Facebook. He is looking at two different posts, but two comments are exactly the same in both, complete with the same peculiar spelling mistake. (00:08:30)
Continuity mistake: In Berlin, Tim and Dan are having a frank chat about the state of the business once Mike left. The wet stains on Tom Wilkinson' shoulders change throughout the scene - particularly obvious when at the end Dan says "We're gonna get this one, Tim" and he answers with his jacket practically dry.

Factual error: Dave Franco mentions the difficulties finding any hotel in Berlin because of Folson Europe and the Oktoberfest, which would be consistent with mid-September; in the year 2014 when the movie is set, Folsom started on the 13th. But he also adds that the G8 is in town, which is a question mark (couldn't have been the G8 Summit as it was not in Berlin but in Brussels, and in June anyway) and, "this week" the Berlin marathon, who took place on September 28th, definitely too late to be in the same week as Folsom.
