Ranbir Kapoor keen on Dhoom series

Mumbai: Bollywood heartthrob Ranbir Kapoor has expressed his desire to be part of the hit `Dhoom` series.
The theme of the series centres around thrill, action, bike chases, handsome thieves, smart and daring stealing plans. After the success of `Dhoom`  (2004) and `Dhoom 2` (2006), there has been much buzz in B-town regarding its third instalment.
Actor Aamir Khan would be seen as baddie in `Dhoom 3` while actors Abhishek Bachchan and Uday Chopra would continue with their famous pair of `Jai` and `Ali`.
"If another sequel to `Dhoom` series comes after`Dhoom 3` then I would love to be part of it. It is a very good franchise. Also given the fact that the script is too good," Ranbir said.
The 28-year-old actor wants to do some action films now and build up his muscles.
"Since `Sawariya` my body has been the same. I have never put on or had to lose weight anytime. For me it is difficult to build muscles because my body type is such that it loses weight easily.
"So I hope at some point of a time I get to do an action film so that I can build up my body, So that I can also look real… like if I hit the villain it should look real," Ranbir said.
Ranbir would be seen next in Imtiaz Ali`s `Rockstar` opposite Czech-Pakistani origin Nargis Fakri. He plays the role of rockstar Jordan. The film is slated to release this September.
Later he will be seen in Anurag Basu`s `Barfee`, a romantic-thriller alongside Priyanka Chopra and Tollywood actress Ileana D`Cruz. The film releases in 2012
