Unlike his previous films Agneepath and Brothers, director Karan Malhotra says he has built a new world in Shamshera, an experience that turned out to be daunting and liberating in equal measure. Both Malhotra's debut Agneepath and Brothers were remakes of popular films, but the Ranbir Kapoor-starrer Shamshera had no reference point, just an idea from film's producer Aditya Chopra. Shamshera: Karan Malhotra Overwhelmed With the Response to Trailer of Ranbir Kapoor-Starrer.

"I kept comparing my movies with the original ones. I could fall back and refer to the original Agneepath and Warrior, the English film from which I adapted Brothers. With Shamshera, it was a more liberating and less burdening process to create a world of mine. It was also the most daunting film for us because we had humongous sets and big crowds. We had no reference point, we had to build the world from scratch," the director told PTI in an interview here.

Headlined by Hrithik Roshan, Agneepath was the 2012 remake of Mukul Anand's 1990 action drama which earned its original lead star Amitabh Bachchan his first National Award. On the other hand, sports drama Brothers, which featured Akshay Kumar and Sidharth Malhotra, was the Hindi adaptation of the 2011 American film Warrior.

Malhotra said his previous films helped him lay the foundation of Shamshera, a 19th century-set action film which follows the story of a warrior tribe living in the fictitious city of Kaza and their fight for independence against British rule.

"Both Agneepath and Brothers have been a vital part of what Shamshera is. While Agneepath gave me the confidence to be able to mount a film like Shamshera, Brothers gave me an insight of what I could bring differently as a filmmaker to make Shamshera," he said.

Every film has played an important role in making Malhotra a "better technician, director and writer," he added. "Shamshera is the biggest film that I have done so far. The world of Shamshera is unlike Agneepath or Brothers. It is much bigger than that."

Although he is an ardent fan of the larger-than-life cinema of the 70s and '80s such as Steven Spielberg's Indiana Jones franchise, the director said his upcoming film bears no similarities with the visuals of the films of that era.

"I have been a huge fan of filmmakers like Mukul Anand, Subhash Ghai and that is the kind of cinema I like. So, my school has not changed. I am a huge fan of films like Indiana Jones, etc. I am a sucker for larger-than-life emotions and situations.

"The world that is presented in (Shamshera) is going to be new, in spite of it being a period film. I hope the audience will discover that this is a fresh take in this space," he added. Shamshera is a period film, not a historical drama, said Malhotra. It is based on a story by Neelesh Mishra and Khila Bisht, with screenplay by Malhotra and his wife Ekta.

"It is a fictional story based in 1871. It is influenced by those times and a few historical movements that had taken place then. But otherwise, the film is completely created out of fiction."

Produced by Yash Raj Films, the movie will see Ranbir Kapoor star in the double role of Shamshera and his son, Balli. Praising his leading man as "a fantastic actor and a brilliant listener", the director said he was confident that Ranbir Kapoor would be able to pull off the two characters.

"The reason why I wanted Ranbir in this film is because he has never done something like this before... Being a great actor starts from being a great listener. Ranbir definitely is that. He surrendered on the sets of Shamshera and he did it brilliantly. Shamshera reunites Malhotra with his Agneepath star Sanjay Dutt, who plays Daroga Shuddh Singh, a ruthless cop tasked by the British to rein in Shamshera's tribe. The film also stars Vaani Kapoor, who essays the role of Sona, a dancer.

Dutt was also his first choice to play Shuddh Singh, the antagonist, he added.

“I knew he would create Shuddh Singh in a way that no other actor can, which is why I went to him. The best part is that he is not a typical villain. He has been a hero and main lead all his life. To cast him as a villain makes it unique. He is such a superlative performer that he will make you fall in love with himself, whether he is playing a hero or villain.” Shamshera Song Fitoor: Ranbir Kapoor, Vaani Kapoor Kiss, Cuddle and Romance Underwater in This Love Track.

Malhotra said normally, a woman doesn't get to do much in an action heavy film but in Shamshera, Vaani Kapoor's Sona is a crucial character. "The kind of characters Ekta and I write, they need to think and say what they feel, stand up for themselves. Vaani is the Hindi cinema heroine in today's time."

"She has it all. She has the confidence of standing up with Ranbir Kapoor or Sanjay Dutt in a film. I always wanted to work with her and Shamshera was the perfect opportunity," the director added. Also starring Saurabh Shukla and Ashutosh Rana, Shamshera is slated to hit the theatres on July 22.
