Unconventional roles excite Bachchan

Iconic Bollywood actor Amitabh Bachchan, whose new film about the obsessive love of an old man for a teenage girl will be released in March, said unconventional roles excite him, an Indian newspaper reported on Friday.

"Nishabd" (Silence) has drawn comparisons with Vladimir Nabokov's controversial 1955 novel "Lolita".

The 64-year-old superstar has played unconventional characters before like "Sexy Sam" -- a widower romancing young girls -- in the hit 2006 film "Kabhi Alvida Naa Kehna".

"I'm still the same man, the same actor. But circumstances have changed, unconventional subjects are being attempted," Bachchan was quoted as saying by Hindustan Times daily.

"And the more varied the roles for an actor, the more exciting the day at the studio".
