'Vikram Vedha' actor Madhavan is reportedly set to do a cameo in Shah Rukh Khan's 'Zero'.  The Hindi-language film, directed by Aanand L Rai, features the Bollywood Khan in the role of a dwarf.  Its teaser was out recently.  

Maddy, as the Kollywood hero is fondly called, is one more actor who is playing a cameo in the much-awaited film.  Salman Khan, late Sridevi, Rani Mukerji, Kajol, Karisma Kapoor, and Alia Bhatt, have already done their bit roles out of respect for SRK.  As cameos go, 'Zero' is a cameos-filled multi-starrer.  

As for Madhavan, he was recently done shooting for Naga Chaitanya-Chandoo Mondeti's 'Savyasachi'.  Should he wow the audience in the film, Maddy can be expected to be busy in Tollywood as well!
