The first film of the Superhero franchise that was started by Rakesh Roshan and Hrithik Roshan was Koi... Mil Gaya in 2003, where the leading lady was Preity Zinta. Three years later, we got Hindi Cinema's maiden Superhero in the form of Krrish with Priyanka Chopra by his side, continuing her rock-solid support in Krrish 3 in 2013.

As far as Krrish 4 is concerned, it was reported a few months back that Kriti Sanon would be the leading lady opposite the actor this time but now a report by Bollywood Hungama states that it's not Sanon but Kiara Advani who seems to be the choice of the makers. The report adds that it was the schedule of the Heropanti actress that didn't allow her to come on board for the drama.
