Model-turned-actress Bipasha Basu, who has come a long way in the industry, says she has always picked up unconventional roles. Be it playing a character with grey shades in her first film "Ajnabee", to playing a sensuous character in "Jism" to her forthcoming horror thriller "Aatma", the actress has defied conventions. "When I started my career, I was 18 years old and I was bored with modelling. I took my first film due to this reason only. I got a lot of criticism for that," said Bipasha, who has done about fifty movies in over a decade. "Many of them said that I am too unconventional, but I never felt bad about it. 'Main karti gayi jo mere samne aata gaya'. At the beginning of your career, you never have a choice. You have to take what comes your way. I have always done unconventional roles," she added. The 34-year-old also did films like "Raaz", "Corporate", "Pankh" among others. Bipasha is currently busy promoting "Aatma", which is slated for a March 22 release
