Ranbir Kapoor will don three different looks in Burfi including a French beard and an aged look.

Says a source, "RK ages from his 20s to the 50s. The different looks are not always visible in the film. It's implied that he ages.

Mostly, he has one look throughout. Ranbir has also grown a little French beard for his character in Burfi for the first time as it goes with the sharpness of his character."

Expanding on the character on Burfi the source says, "Though he is deaf and mute he is also totally wily, humorous and very sharp a go-getter with a wicked streak and warm heart.

He is a small-time crook from Darjeeling always out-smarting the cops. Normally, physically challenged people are shown in a tragic light trying to draw sympathy from the audience.

But he will keep the audience amused with his antics he is too smart a cookie!"

Burfi is a small-town crook of the 1970s. "It's not a contemporary film based in 2011 as the story has a base in the emergency and Naxal movement, though it's just an outline for the story but not the main story.

The film will be shot in Mumbai, Darjeeling and Kolkata and is a romantic-comedy."
