The filmmaker's latest project co-stars Ajay Devgan and southern star Tamannaah.
He told The Times of India: "Himmatwala is one of my top five favourite Bollywood films. I am very fortunate that my name is associated with the movie.
"The film is a rewrite, and not a remake, based on the original film. The essence of the original film is there in my version, but my treatment is completely different.
"The scenes and the characters in my version of the film are completely different. I have added some nuances like slightly over-the-top acting, typical filmy scenes between mother and son, which today's youths wouldn't have experienced."
In February, Khan revealed that Devgan hated doing the musical sequences for the role despite dancing "really well".
Khan has previously said that he revived the 1983 film because the decade was "special" for him.
The original film co-starred Sridevi and Jeetrenda as a couple who fall in love despite family grievances.
