This is the first film where the Chinese government has allowed a fight to be shot on the Great Wall.
This film is banned in Nepal for suggesting that Buddha was born in India. Buddha was actually born in Lumbini, which is in Nepal.
The fight on the Great Wall was shot in seven days. It was originally planed to be shot in 20 days but the Chinese government would only allow for seven days for tourism purposes. Those seven days were extremely busy; Akshay Kumar, who usually shoots for only 10 hours a day, had to shoot for 18 hours in chilly conditions on the Wall.
Akshay Kumar is a big fan of co-star Chia-Hui Liu, having watched Liu's The 36th Chamber of Shaolin (1978) about 100 times.
At the end, Akshay Kumar is shown giving a hint about a sequel named 'Chandni Chowk to Africa' which was never made.
