Ranbir Kapoor is extremely courageous: Karan Johar

Ranbir Kapoor is damn excited about Wake Up Sid. "When Ayan narrated the script - it was a 4-hour marathon session - I knew I had to be a part of it. Nothing else mattered. All I knew was, I had to do this film. That was the impact of its story," Ranbir tells me.

Ranbir's one gutsy actor and the best part is, the films are diverse in content. If there's a coming of age Wake Up Sid, there's also a rom-com Ajab Prem Ki Ghazab Kahani, a black comedy Rocket Singh or an intense Rajneeti. "I never made a conscious decision. I received several offers, but I chose to do films that would appeal to me first and foremost," Ranbir reveals.

Meanwhile, the supremely talented actor has done a remarkable job in Wake Up Sid, feels Karan Johar. "Ranbir has the power to hold a scene, which very few actors can boast of. Also, his choice of films is incredible. He's extremely courageous," Karan states.

Once Ranbir completes Rajneeti, he moves on to Siddharth Anand's film, which will be produced by Sajid Nadiadwala. "That's the only film I've signed," he clarifies.
