Annie is shown traveling around London in a Black Cab registration LX45QSZ then shows her disembarking from a Burgundy colored taxi registration LX75SVG then later on she hails a taxi with the registration LX45QSZ.
The vehicle registrations used on the cars in UK are wrong, the Lexus in which Annie is given a ride in has a registration that will be issued in 2014 and has the wrong font used to be road legal in the UK. The Toyota 4x4 has a registration that will be issued in 2018, the black London cab has a registration that will be issued in 2045 and again in 2025.
When investigating the nightclub in London, the power sockets shown are the North American kind and not the UK 3-pin plug variety you would expect.
Where Annie's sister and niece are waiting outside to go into the Smithsonian, a ROM poster (Royal Ontario Museum) complete with the ROM's museum logo can be clearly seen.
