Ranbir Kapoor has a new challenge to face. While most actors are shedding their muscular look for a leaner one, Ranbir Kapoor has to go manly and brawny for both Siddharth Anand's ‘Anjaana Anjaana' and Imtiaz Ali's next.

So far, Ranbir has been seen playing boyish roles where his character has only just stepped into maturity.

This will be the first time he will be playing a grown-up kind of a role. In ‘Anjaana Anjaana', he needs to match his appearance with that of his co-star Priyanka Chopra, so as to not look younger than her. In Imtiaz's film too, Ranbir will play a manly role.

For his films, Ranbir is undergoing training at the gym to build his muscles. He has confirmed the news and added that a change is good.
