According to sources,"In both the films the main character feels like a loser who must fulfill his destiny by rising to an occasion and fighting the demons who want to destroy the empire. CCTC is actually KFP meets Bollywood."
A few similarities seen in both the films are that in Kung Fu Panda the main character is a panda and is voiced by Jack Black who is a cook. In Chandni Chowk to China the main character is Akshay who is a cook himself, and his name is Sidhu. In KFP, Po leaves his hometown to fulfill his dreams while in Chandni Chowk To China Sidhu leaves Delhi to go to China to fulfill his dreams. After leaving home they both tend to overcome their weakness and learn martial arts on reaching their destinations. Both the movies are based in China with Kung Fu and royalty.
It's also said that the potato slicing scene which is shown in the promos of Chandni Chowk To China is also similar to a scene in KFP where Po is shown slicing vegetables. The only uncommon factor in both these films is that Chandni Chowk To China is a live action film and has a heroine who is paired opposite Akki while KFP was an animated flick without any love angle to it.
When asked the producer Rohan Sippy about the similarities between both the films he said that he had not seen KFP but as per the stories he has heard there seem to be a few similarities. But he also said that Chandni Chowk To China was written three years back and the story is based on modern day China so it's just a matter of co-incidence that so many similarities have cropped up.
The director of the film Nikhil Advani was not around for any comments.
Akshay Kumar starrer Chandni Chowk To China (CCTC) is said to be inspired by Hollywood's animated blockbuster Kung Fu Panda (KFP).
