Yash Raj Films' "Dhoom 3" is ready to come out Dec 20 and producer Aditya Chopra, looking for a unique marketing strategy, won't settle for anything less than a "never before idea" to promote the movie.

"Aditya Chopra has told his entire team that until there is a 'never before idea', they should not even discuss anything regular, " said a source close to the production house.

"All marketing initiatives from theatrical launch to music launch to every other activity will be done in a never seen before avatar, " the source added.

Directed by Vijay Krishna Acharya, the third film in the "Dhoom" franchise film will see Aamir Khan in a negative role and he will be joined by the likes of Abhishek Bachchan, Aditya Chopra and Katrina Kaif in the cast.
