Apparently, Sanjay, who is producing the film, and David, wanted someone who could be sexy and funny at the same time. Both felt that only Kangna could do it, so David approached her. Kangs liked the part and agreed to do the film.
This will be Kangna's second film with both the heroes. Her Knock Out with Sanjay and Once Upon A Time In Mumbaai with Ajay are waiting to be released.
Rascals will also have a third male lead, who is yet to be finalised.
