/> Why was Chitrangda Singh suddenly replaced by Jacqueline Fernandez in the mutant's role in Krissh 3? Though both the parties give the age-old excuse of date problems, there is more to this parting of professional ways than meets the eye.

Apparently Chitrangda was not comfortable with some of the requirements for the role.

Says a source, "Initially Chitrangda was most excited about the mutant's role. She had begun to read up as much as possible on the subject and had even begun physical preparation. The clothes, makeup, body language and speech quality were all discussed. Chitrangda had even begun to train in martial arts and had taken off to the US to try Accelerated Free Fall. "

According to the source, it was certain scenes showing the mutant's transformation that made Chitrangda uncomfortableSays the source, "Though the mutant's role is stupendous it does require the actress to get down to an elemental level of self-revelation. That's where the problem came in. "

Jacqueline who recently re-definied on-screen uninhibition for Murder 2 has happily stepped into the mutant's part.

Interestingly she played an ET in an earlier film Jaane Kahan Se Aayee Hai. So playing aliens probably comes naturally to her.

When contacted Chitrangda said, "I can only say there were date issues.... I tried to sort it out. Couldn't manage. "

Added Rakesh Roshan, "Actually I was to start the film in October and had taken the dates accordingly. But now I've shifted the film to December. Chitrangda tried her best to give us dates in December-January. But I think she has some family commitments. So she couldn't accommodate us. I had to opt for another actor. "
