Nikkhil Advani has assisted Sudhir Mishra and co-wrote the screenplay (with Sudhir Mishra and Shivkumar Subramaniam) of the movie Is Raat Ki Subah Nahin (1996).
Nikkhil Advani has directed India's first stereoscopic 3D animation film, Delhi Safari, which was released in October 2012.
Nikkhil Advani had planned to make a movie on Operation Blue Star, a military operation ordered by Prime Minister Indira Gandhi in order to take control over the Harmandir Sahib Complex in Amritsar, Punjab, which was occupied militant religious leader Jarnail Singh Bhindranwale. However, in May 2017 he announced he has shelved the idea citing the controversy surrounding the operation.
