Gulshan made his debut with Bejoy Nambiar's "Shaitan" in 2011.
"It was great working with Sanjay Leela. I worked with great freedom. Whatever ideas I used to have for my character, he used to let me experiment," Gulshan told reporters Wednesday at the premiere of his film "Prague".
"It would be wrong to say that one cannot work freely with Sanjay Leela Bhansali. Those who say this, they don't know the filmmaker very well," he added.
Set in the backdrop of Gujarat, the film is said to be an adaptation of Shakespeare's epic love story, "Romeo and Juliet". The film is set for release Nov 29. Gulshan is also in awe of his co-actor Ranveer Singh who plays the lead in the film opposite Deepika Padukone. "Ranveer is very energetic. Whatever he does, he does it the best. Perhaps there is nobody like him. He is unique," said Gulshan.
