Ranbir Kapoor, who is all set for his second release "Bachna Ae Haseeno", says constant comparisons with his father Rishi Kapoor are inevitable, but feels that he won't be able to match up to his father's on-screen charisma.

"I know the audience seeks another Rishi Kapoor in me. But I can never be like him. He is such a spontaneous actor, " Ranbir told.

Interestingly, a hit song from his father's film "Hum Kisise Kum Naheen" inspires the title of his second film "Bachna Ae Haseeno".

If given a chance to act in the remake of his father's super hit "Bobby", Ranbir said he would love to romance Dimple Kapadia on screen.

"No one can play the role of Bobby like Dimple Kapadia did. She is still so beautiful and I would love to woo her on screen again if a remake is made, " said the actor.

Ranbir was in town to promote "Bachna Ae Haseeno" that is releasing Friday. He will be seen romancing Minissha Lamba, Deepika Padukone and Bipasha Basu in the movie.

Talking about his role, Ranbir said it is not that of a Casanova as the title hints. "I play a next-door boy and the film is about his love life at different phases of life."

The actor says he wouldn't like to be confined in lover-boy image.

"In both 'Saawariya' and 'Bachna Ae Haseeno' I play a lover boy, but won't keep myself confined to that particular image. Give me two years and you will find me beating up goons and kicking in the air, " said Ranbir who is expecting his film to do well at the box office.

"My first film 'Saawariya' was not a commercially hit one, though it was the best possible launch that one can ever have. But this time I expect my film to be a commercially hit one."

As for romancing his real-life love interest Deepika in the film, he said: "Both of us have just started our career. We would appreciate if people talk about the film and our characters instead of linking our personal life with the romance on-screen."

He also pointed out that Hindi film industry has grown highly competitive in the last couple of years and as a result all actors have to constantly reinvent themselves.

"Right from Amitabh Bachchan to Darsheel Safary - Bollywood has never been so competitive. Every day a new actor takes the reign. As a result we actors have to constantly groom ourselves, " said Ranbir.

His other films are Prakash Jha's "Rajniti" and Rajkumar Santoshi's "Ajab Prem Ki Gazab Kahani".
