But we also spotted quite a few stars - including John Abraham, Ameesha Patel, Narmada Ahuja, Chitrangada Singh - who turned up to watch KJo's latest offering.
David Dhawan said he and his wife couldn't wait to see their son on screen.
"Can you believe it, we haven't seen a single frame of Varun's work as yet!" David said.
The one person missing from the screening was Alia's elder half-sister Pooja Bhatt. The actress-turned-director said she would prefer to watch Alia with the audience at a public screening - first day first show.
"I'm going to see it first day first show on Friday. I can't wait," said Pooja. "I do have the option of seeing it the night before. But I'd rather see it with an unprejudiced audience.'"
"I've watched most of my own films on Friday with the ticket-paying public."
