Raveena Tandon to play negative role in 'Shab'

After three years gap, Bollywood actress Raveena Tandon will be seen playing a negative role in Onir's upcoming romantic film 'Shab'.'.Raveena, 41, who is making a comeback to films after a gap of three years, said she wanted a challenging role to make her return to Bollywood."I really wanted to do something challenging and fun. I opted for 'Shab' because Onir is a dear friend and the character which I am playing in the film is something which I didn't do earlier. "It's a role of a diva but has shades of grey in it and in the film I walk through a very thin line between positive and negative. Onir gave me the other role first but I wanted this role because I have not played such a character before. I was more excited to play the negative part," Raveena told
