"I am confident about this film. If you consider the film's trial at Cannes (film festival), we received a standing ovation there. So definitely for the audiences here I am very confident because the product is good," lead actor of the film Nawazuddin Siddiqui said.
"We have put in a lot of hardwork. It remains to be seen how it gets response here but I hope people here will like it," he added.
Nawazuddin plays a character based on the real-life psychopathic serial killer Raman Raghav from the '60s.
About the compliments coming his way for his performance, he said, "I was compared to Anthony Hopkins and Heath Ledger. They are such big artists I don't have the same status as them. They have written it in the reviews. It seems so huge for me. It's great, thank God"
His director Anurag Kashyap and co-stars Vicky Kaushal and Sobhita Dhulipala were also present on the occasion.
The screening was also attended by actors Kangana Ranaut, Gulshan Devaiah Shweta Tripathi, Vivaan Shah and filmmakers Siddharth Roy Kapur, Aneez Bazmee, Navdeep Singh, Abhishek Chaubey and Vikas Bahl.
Siddharth Roy Kapur said, "I am very excited. Anurag Kashyap and our relationship is quite old now. We made 'Dev.D' together and since then I have always been a fan of his work."
He added that "Raman Raghav 2.0's" trailer is "spectacular, very interesting and intriguing".
"What I admire about Anurag is that he is not scared of taking risks. Some risks work, some risks don't. But he never stops trying and that I think is most amazing about him as a filmmaker," Kapur said.
Vikas Bahl, one of the producers of the film as part of Phantom production house, said: "Anurag is a strange filmmaker. There is no other filmmaker who narrates the kind of stories that Anurag does. It is interesting if someone has their own unique stories to tell. And Anurag, to me, is one of the most exciting filmmakers." 'Raman Raghav 2.0' releases on 24 June.
