"It's my first film and obviously, I've been really nervous and anxious. But thankfully Aamir sir took time off from 'Thugs...' to help me wrap the post-production of the film," Chandan said in a statement.

"He came and gave his approval to the VFX and DI (colour correction) in the film. He spent the last few nights fine-tuning the final sound mix. He insisted on watching the first copy before he left to promote the film and once I had his final approval on the complete product, I've been sleeping peacefully."
