Singh Saab The Great: I am my biggest critic, says Sunny Deol

New Delhi: Actor Sunny Deol says he is the biggest critic of his work and knows it very well when his performance is not upto the mark.

The 57-year-old has been a part of movies like 'Darr', 'Gadar: Ek Prem Katha' and 'Yamla Pagla Deewana'.

"I am my biggest critic. I know best where I am right and wrong. At times you will not see me happy when people say, 'Wow, what a shot'. I feel, 'What was this, I didn't deliver what I want to'," said Sunny, whose latest movie 'Singh Saab The Great' released Friday.
