Mumbai: Siddharth Anand's next venture features Hrithik Roshan and Tiger Shroff,
and the director says the real challenge is getting a story that does
justice
to both the actors.
"It's the script that plays a crucial role
here as both the actors should feel that their roles are good enough and
feel secure as well. For the two-hero films, the challenge
lies in writing and not casting," he told PTI.
