"Haider" is said to be the director's adaptation of William Shakespeare's 'Hamlet'.
"I thought it is justified. When I read the script, I found it very interesting and I have tried to do something shocking whenever I have worked with Vishal. With him I have always tried to do something different," the actor said here at a promotional event of his upcoming release "R...Rajkumar" Friday.
Meanwhile, Shahid also admits that one of the best performances of his career was in Vishal's film "Kaminey", which released in 2009.
"He is a phenomenal director. He has given me 'Kaminey'. It has been the most appreciated role of my life till now. It's great working with him again. It has been a lot of fun," said Shahid.
"Haider" also stars Shraddha Kapoor in the lead.
