The film starred Sunny Deol and Amisha Patel in the lead.
"If today I remake 'Gadar' I can understand it will be very successful. But only for the sake of business I will not spoil my 'Gadar' because this film will be remembered even after 100 years for Sunny Deol and myself.
"I want to be alive even after 100 years and it can only happen because of 'Gadar'. So I will not go for 'Gadar 2' until and unless I get that strong story," Sharma said here Thursday at the teaser launch of his next film "Singh Saab The Great".
The director accepts that a sequel can make good business and "Gadar" sequel will generate curiosity among the audience, and thus generate great business.
"Second part is always a good business proposition. I know the level of curiosity will be very high if I would make 'Gadar 2'. But 'Gadar' was such a big hit, probably the biggest blockbuster hit of Indian cinema.
"So much is talked about box-office numbers these days but it was the first film that crossed 100 crore rupees in 2001, in today's times it's a thousand crore," said Sharma.
Anil is currently gearing up for the release of his directorial "Singh Saab The Great", starring Sunny Deol in the lead.
'Good cinema was started by Sunny Deol's films'
Filmmaker Anil Sharma feels that actor Sunny Deol brought the trend of good cinema to Bollywood.
The director-actor duo has worked together in movies like "Gadar: Ek Prem Katha", "The Hero: Love Story of a Spy" and "Apne".
Tracking Sunny's film journey, Anil said the actor is the harbinger of modern cinema in India and he, in fact, did it with his debut film 'Betaab' in 1983.
"I feel the cinema which is considered good cinema in India was started by Sunny's films. The kind of films like 'Arjun', 'Betaab' which he did in the starting of his career and the kind of directors with whom he worked, it led to the entry of modern cinema in India," said Sharma here Thursday at the teaser launch of his next film "Singh Saab The Great".
Meanwhile, Anil asserts one has to be very sincere and logical if Sunny has to be roped in for a film and this is something which has not changed about the actor with time.
"He has worked with best of the directors. So I always knew that to work with him one has to be very sincere, hard working and logical. Since the time I have worked with him for the first time till today he demands the same logic and sincerity," said Sharma.
Sunny will soon be seen as a Sikh in Sharma's next project "Singh Saab The Great", which is slated to release in November this year.
