Continuity mistake: After meeting Elise on the bus and getting his Blackberry dumped into his coffee David Norris calls his friend Charlie with his "spare phone" (silver).

Continuity mistake: When Eddie walks in to the doctor's office and talks to "brows gone wild" the woman with the green shirt has it kind of loose around her breasts.

Continuity mistake: George is in his dressing room, holding a tissue in his right hand. When the shot changes, the tissue has moved to his left hand.
Other mistake: Jacob takes Cal shopping. In the shot during which Jacob says to Cal "the skin under your eyes is starting to look like Hugh Hefner's ball sack," the film is flipped and the viewer is watching a reverse (or mirror) image. This is revealed principally by the fact that the emblem on Cal's Polo shirt is on the right side of his chest as opposed to his left.

Audio problem: In Notes II, Madame Giry voice is out of sync as she says,"Fear his fury.".
Factual error: During scenes set in the early Noughties (one of Dex and Emma talking on a rooftop at night, and another of Dex crossing the river on a bus), modern buildings are shown on the skyline, including the Heron Tower (2009), the tallest building in the City at the time of filming, but it didn't exist at the time the scene is set.
Other mistake: At the beginning of the trip we see close-ups of the passports of the three girls being stamped. The date is 19 Jun 2010. During the climax of the movie Emma's boyfriend puts a copy of "Le Parisien" on the counter, and the date there is Jun 10 2010. (00:12:00 - 01:26:20)
