"I have worked really hard for my up coming movie #RamanRaghav2 and I believe this is my best performance by far," he tweeted during a chat with his fans.

The 'Bajrangi Bhaijaan' star says the prep behind a good performance does affect him personally.

"When you take something from a character you play, the character takes something out of you too," he said. When asked who inspires him, Siddiqui named veteran actor Naseeruddin Shah his idol.

"The actor that I admire the most is @NaseerudinShah. I always find his work to be outstanding!," he said.

Directed by Anurag Kashyap, 'Raman Raghav 2.0' releases tomorrow.
