"I think only a new actor should portray the role because the USP of 'Aashiqui' was a new boy who had no image. If you look at it, people didn't know what to expect," the 44-year-old said here Wednesday at a fashion show organised in memory of late director Sultan Ahmed.
Asked if he would like to do a special appearance in the film, Rahul said: "No, I do not want to do it. There is a lot of difference between Rahul Roy of that time and Rahul now. The innocence I had 22 years back, that innocence can never come back."
Being directed by Mohit Suri, the romantic musical has Aditya Roy Kapoor and Shraddha Kapoor in the lead roles and both have appeared in other films.
"Someone corrected me that Aditya and Shraddha are doing the roles. I think both of them don't have any particular image and I think both should be absolutely right for the role," he added.
Rahul asserts the storyline of the remake has to be very different from the 1990-flick as the definition of romance has changed.
"Mohit is a good director. I can't say what heights will this new film touch but this is evident that the story would be different because there is a lot of difference between romance then and romance now," Rahul said.
