"Doing four films now: Zoya Akhtar's next, 'Jeene Do', a soulful love story, a Bengali detective film and the sequel to 'Mr. and Mrs. Iyer'," Rahul shared during an interactive session with his fans on micro-blogging site Twitter.
He is currently shooting in Kolkata for a month.
"For most actors, I imagine filming is a busy time. For me, compared to the rest of my life, it's the most peaceful," he added.
Rahul has earlier delivered noteworthy performances in films like "Mr. and Mrs. Iyer", "Chameli", "15 Park Avenue" and "The Japanese Wife".
