Though Ranbir shakes a leg real smooth Imtiaz Ali doesn't want him to groove as he believes the character, inspired by Jim Morrison, would look sissy.

One will see Ranbir Kapoor doing the head bangs and playing the guitar but don't expect the Kapoor boy dancing in Imtiaz Ali's Rockstar. The director strictly feels that Ranbir shouldn't be dancing in the film as it is contrary to the image of a rockstar.

In the film Ranbir plays a huge Jim Morrison fan. While songs in the film will evoke the vibe of the swinging rock genre, Ranbir will not be doing any Bollywood jhatkas, the staple of choreography in tinsel town.

According to a report, "Director Imtiaz feels that no rockstar has ever danced and it will look very weird and not in character. He has strictly said no to dance moves. Imtiaz wants Ranbir to get under the skin of the character and not merely behave like one by only playing the guitar."

The report continues, "There is a song with his co-star Nargis Fakhri, but whether he will dance remains a mystery. Imtiaz is yet to figure out the 'dancing' aspect of his film. At the moment they have shot for a gypsy song with montages of Ranbir coming in."
