He needs to lose weight fast to look compatible on screen with the Tamilian maverick Kamal Haasan's daughter Shruti Haasan who makes her debut alongside Maddy in a Tamil film to be directed by the Marathi director Nishikant Kamath.
Divulges Maddy, "Until the contract was signed we weren't allowed to announce Shruti's name. It's a love story with a strong thriller format.
I had gone to the UK and lost over 10 kgs last year. But then for Nishikant Kamat's Tamil version of Dombivali Fast I had to go back to looking like a blob. So I'm back to weighing 80 kgs.
But to look compatible with Shruti (who's about 10 years Maddy's junior) I've to bring my weight down to 74 kgs. And I've to do it immediately!"
Maddy has been given a time frame to get into youthful shape. "When you're overweight it's not difficult to lose some pounds. But when you're normal in weight bringing the scale down is tough."
The film with Shruti has no title yet. It has music by Shankar-Ehsaan-Loy.
Madhavan's Yenalu Orvan, the Tamil version of Dombavli Fast has been a great experience for the actor.
" To begin with, the collections were average. But the film picked up by word of mouth and the glowing reviews. I am going to make money as a producer. But no more production work for me.
A producer's job is too tough. Acting is tough enough.I did want to do Imtiaz Ali's Jab We Met in Tamil. But someone else has bought the rights."
Currently Maddy is doing a Hindi-Tamil supernatural thiller called Channel. "It's about a family who comes to live on the 13th floor of a building. All sorts of eerie things happen to him. It's our own Sixth Sense which I hope makes sense."
Neetu Chandra is Madhavan's co-star in this spook fest. Vikram Menon directs the film.
