After two back-to-back sober-and-thoughtful roles as a wannabe singer and wannabe actor respectively, Farhan Akhtar will for the first time try his hand at comedy in Kartik Calling Kartik.

"Not that Kartik is a full-fledged comedy. It's a thriller. But it has a lot of light funny moments, something that I missed out on in my first two, actually three (the unreleased acting debut in The Fakir Of Venice) starrers on doing any of the light-hearted stuff," explains Farhan.

Strange, considering Farhan is well- known for his sense of humour in real life. "I don't know why I've been cast in such serious parts so far."

Besides Deepika Padukone who plays the female lead, Kartik Calling Kartik also stars Shefali Shah and Boman Irani.

"We start shooting in April," informs Farhan who also plans to cut a music album. "But for that I need to take out a chunk of time and devote my full attention to it. Singing is not just a hobby. It never was. I need to pursue it seriously. And not only because of Rock On. I can't just have someone else composing the songs while I go in the studio and record."

Farhan has just completed his innings as a chat-show anchor on 'Oye! It's Friday!' In the last episode we saw him with cricketer Sourav Ganguly and Kangana Ranaut. "I don't think I've had so much fun before. I'm a huge cricket addict and Sourav was a delight. And I'm amazed by how relaxed and natural Kangana is."
