Poonam Sinha is in awe of her daughter Sonakshi's performance in her forthcoming film "Lootera" and says now, even her father, veteran actor Shatrughan Sinha, will think twice before advising her on anything after the film.

"After the film, I think her father will also think twice before advising her or teaching her something because she has given a brilliant performance," Poonam said here at a special screening of the film.

Directed by Vikramaditya Motwane, "Lootera" is a period romance set in the 1950s. She is all praise for lead actor Ranveer Singh's performance in "Lootera", coming out July 5.

"Ranveer and Sonakshi, both, have done brilliantly well. A mother doesn't consider her children that talented, but when outsiders say, she agrees. But I think I have to bow down to Ranveer and Sonakshi's work in the film," she said.

Poonam believes "Lootera" will be remembered as a classic film in Indian cinema.

"It is a classic film. I think it will go down in the history as a very well-made film by a very young and talented director who actually has brought out such brilliant work from both his artists, in fact, everybody if you ask me," she said.
