Bahl, who earlier helmed Kangana Ranaut starrer "Queen", said they have a good chemistry.
"I always felt that they look good on-screen. They have a good chemistry in the movie," Vikas told PTI.
In "Shaandaar", Shahid is a wedding planner, Jagjinder Joginder, who is organising the marriage function of Alia's sister.
Asked if he was not apprehensive to cast Shahid in a fun film post his serious stint in "Haider", Vikas said, "There is no pressure like that. He has hardly done intense roles like 'Haider' but he is a fun actor. This is his space and he enjoyed doing the film. We had a lot of fun."
Co-produced by Phantom Films, Karan Johar's Dharma Productions and Fox, "Shaandaar" will hit theatres on October 22.
