This is the first film where the Chinese government has allowed a fight to be shot on the Great Wall.
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.
At the end, Akshay Kumar is shown giving a hint about a sequel named 'Chandni Chowk to Africa' which was never made.
First Indian production to be shot in China.
Akshay Kumar claims that this film is semi-autobiographical: Sidhu is a cook who grew up in Chandni Chowk, Delhi, just like Kumar had.
