"It's story and scenario were written by Chopra" - its
"The cinematography was done by Binod Pradhan, while the editing was performed by Renu Saluja." - I would recommend rephrasing this sentence to Binod Pradhan served as the film's cinematographer, while the editing was performed by Renu Saluja.
I would recommend either expanding the lead's second paragraph (on plot) or merging it with the third paragraph, per WP:LEADLENGTH
"Chopra conceived the film after his low-budget suspense thriller Khamosh (1985) with unknown cast, failed to find" - 'with unknown cast' sounds a bit clunky here, I'd recommend getting rid of it so it reads smoother: Chopra conceived the film after his low-budget suspense thriller Khamosh (1985) failed to find
"Knowing this, Kishan book's a flight for Karan to Delhi" - books
"In the fear, Karan leaves" - perhaps try something like Karan leaves, in fear of his life
" Karan kills Francis instead and joins hand with Musa" - 'joins hand' doesn't make much sense to me. Deleting 'hand' should be OK
"Anna goes out to kill Musa, beliving him behind the murder's of his men" - believing and murders
" Shroff was initially hesitant to do the film, since he didn't want to get typecast" - did not (WP:CONTRACTION)
"The headquarter of Patekar's character shown in the film" - headquarters
"While filming the final scene of the film involving fire, Patekar got burnt and the screams heard in the film are real" - the latter half of this sentence sounds quite informal. How about While filming the final scene of the film involving fire, Patekar suffered from serious burns.
"The films climax was shot at the Gateway of India" - missing apostrophe
"Some sequences were also shot at babulnath temple" - shouldn't this be in capitals?
" The film is shot and set in Mumbai." - this needs to be in past tense (was shot)
"due to its depiction of voilence" - typo (violence)
"he soundtrack album of the film was released on January, 1989" - released in January 1989
This film must be quite realistic it the lead actor actually got burned on set! I've done some copyediting throughout the article, if that's OK. I mostly spotted some typos and a few sentences could be rephrased but if all of the above are addressed then this should be good to go. It's well referenced and I couldn't find anything wrong on the sourcing side of things. JAGUAR15:30, 19 November 2017 (UTC)[reply]
