Factual error: Peter and Lizzie are shown driving out of London in the early evening summer sun to escape to Peter's home in Brighton. This is about half way through the film. There is a clear shot of the car driving west on the A4 out of town. As Brighton is directly south of London this is definitely not the way you'd drive. If you wanted to go to Brighton from central London you'd take the A23/M23 all the way.
Revealing mistake: Before Peter Colt plays his first round match there is an aerial shot panning across the Wimbledon complex with the commentator declaring, "this is the first day of Wimbledon." However, the aerial shot shows most of the courts are badly worn, as they would be at the end of the tournament. On the first day they, are always lush and green. The shot was taken from archive footage showing the end of a Wimbledon Championship.
Continuity mistake: On the London Eye, Peter and Lizzie are looking at the Houses of Parliament from quite a height, so they've got around ten minutes before they're back on the ground (a "flight" takes around 30 mins). Jake walks up, Peter punches him, then immediately they run off in the hubbub afterwards, suddenly back at ground level.

Factual error: Men's final day is held on the second Sunday of Wimbledon. However, at 7am on the morning of Peter Colt's final appearance, we hear the radio greeting of Radio 1's Chris Moyles. Moyles is a weekday not weekend breakfast DJ. This would only be possible if the final were held over from Sunday to Monday because of sustained poor weather, which didn't happen.
