A lie about Prabhas, most likely
It's being said that Sanjay Leela Bhansali wanted to cast Prabhas as Ratan Singh in his magnum opus 'Padmaavat'. On the face of it, this must be a joke.
The way Bhansali visualized the story of his film, it was about Alauddin Khilji's depredations and Rani Padmini's heroic exploits. Ratan Singh is there but only as someone who can't protect himself from the Islamic invader. It's inconceivable that a sensible director like Bhansali would have cast Prabhas in such a role at a time when the audiences were in awe of the 'Baahubali' franchise.
People can watch Shahid Kapoor being dominated by Deepika Padukone. But would they have watched Prabhas being overwhelmed by his heroine? If we know the answer is a 'No', a director of Bhansali's stature must have known it as a matter of common sense.
