Gupta started his career with Aatish: Feel the Fire (1994) starring Aditya Pancholi and Sanjay Dutt. Later he went to write and direct films including Ram Shastra, Khauff and Jung. The filming of Jung (2000), lasted over two years.[4] While filming Kaante in the Los Angeles in 2001, the events of the 9/11 attack forced the film to relocate planned scenes from several areas that were then considered sensitive.[2] Commentators noted a similarity in Kaante to Quentin Tarantino's film Reservoir Dogs. Gupta said that he was inspired by a number of other films as well, including The Asphalt Jungle, The Killing, and the film that inspired Reservoir Dogs, Ringo Lam's City on Fire. Further, responding to allegations of plagiarism, he went on to state that he would "beg, borrow and steal from any medium, be it films, newspapers, magazines, novels, reality, fiction, to make an interesting story."[2]
Gupta's Zinda (2006) has been described as an unofficial remake of the Korean film Oldboy.[5][6]
On December 24, 2019, he made an announcement on the acquisition of Yali Dream Creations' Rakshak.
