Bollywood actor Kangna Ranaut has been asked by filmmaker Rakesh Roshan to reduce five kilos for his upcoming movie 'Krrish 2'.

Kangna was asked to cut down more weight as she is likely to play the role of a superwoman.

The film will feature B-town star Hrithik Roshan in the lead role.

Kangna is trying her best to reduce her weight and fit into the role.

She will be seen playing a mutant, a character which has rarely been played in Bollywood.

Kangna has earlier shared screen space with Hrithik Roshan in 'Kites' but in that film it was Mexican actor Barbara Mori who grabbed all the eyeballs.

For her role as a muscular superwoman, Kangana is training hard in various combat forms.

Earlier, Chitrangada Singh and Jacqueline Fernandez were offered to play the role but Chitrangada backed out by citing date issues and Jacqueline also turned down the offer.

Hrithik had also featured in the film 'Krissh'. The film scored well at the box office.
