Tricky to get him to collaborate: Dulquer on film with Mammootty

Dulquer Salmaan said getting his father and actor Mammootty to collaborate with him for a film is "very tricky". "He's very proud...that we both have our own identities...I don't think he wants it to get diluted," he shared. "I do want to do something [with him], even if I'm in the same film...not in the same frame," he added.
