Her period drama "Lootera" is set in the 1950s and to play her part perfectly, Sonakshi Sinha has taken yesteryears actresses Madhubala and Waheeda Rehman as her reference points.

Many feel she resembles Reena Roy, but Sonakshi has reason to think about the two legends of Indian cinema.

"I think she (Reena Roy) came after 1950s in the industry. I would think of Madhubalaji, Waheeda Rehmanji, and Suchitra Sen. I can only think of these faces. I am quite excited about the film. I am really looking forward to it, " Sonakhi told reporters at the first look launch of "Lootera" Friday.

"The role has been the most difficult till now. It was quite challenging, " she said and added she would do both kinds of roles like "Rowdy Rathore", "Dabangg" and "Lootera" as well."

Set in West Bengal, "Lootera" is Vikramaditya Motwane's second directorial venture after much acclaimed "Udaan".

Thanks to his storytelling technique and freshness in the narrative, Motwane became a name to reckon with after the success of "Udaan", which had wowed cinegoers at Cannes fest.

But he doesn't feel any pressure.

"I do not feel the pressure. I am not bothered. Rather, I am very much proud of the film. I hope people like it. I want everyone to enjoy the film, " he said.

"Lootera" is said to be inspired by American author O Henry's famous story "The Last Leaf", but Motwane clarified saying, "We have been inspired by the book, but we haven't adapted it. We have made changes in it. It is a fresh film."

For the male lead, Motwane has cast Ranveer Singh.

Jointly produced by Phantom Films and Balaji Motion Pictures, "Lootera" is slated for a July 5 release.
