Factual error: When Julia Roberts takes a photo of Natalie Portman crying she uses a 35mm camera. The final photo in the gallery is from a Hasselblad type camera shooting a square format. All the prints show the full negative and the outside area of the negative. Also when she uses the 35mm camera sometimes she advances the film manually and sometimes you hear a motor drive. It would be either one or the other. Last she doesn't focus the lens when she takes a picture.
Factual error: Jude Law and Natalie Portman are chatting on bus number 109, signed 'Westminster' and driving up Whitehall. Route 109 goes from Brixton to Croydon and nowhere near Westminster, and does not use the old Routemaster bus they are on.
Factual error: When Clive Owen is chatting on the internet to who he thinks is Anna, you can see the URL in web browser. The domain used is "www.nopop.", with a period after it but no top-level suffix, e.g. "com". Even if "nopop" was the top level, which is possible in more modern times but not then, the period after it would stop it working.
Suggested correction: No he's not.
The mistake is valid. After Larry says "Buster", we see Dan standing at an angle with his back towards the opening of the door and doorknob and his left side closest to the door. In the next shot, he's turned more than 90° so that his right side is now closest to the door opening and doorknob.
