But when we watched it, we felt we could have been part of the whole thing.

More like Tim Burtons Gotham City.

Before being canceled, the filmmaking duo were told thatBatgirlwould have likely been scheduled after the release ofThe Flash.

‘The Kings of Kings’

I felt like a kid on set working with Keaton, Bilall said.

I totally forgot that I was directing.

Adil added, Its the biggest disappointment of our careers.

But its a bittersweet feeling.
