Yashpal Sharma's character in this film is canninly named as "Sudhir Vinod" which is reference to the lead characters of the film Jaane Bhi Do Yaaro who were named after its Asst. Director Sudhir Mishra and Production Controller Vidhu Vinod Chopra.
The lead characters take photographs in the park which reveal a murder in progress (after "blowing up" the snaps). As a nod to the source, the park in the movie is called "Antonioni Park" after the director of the original.
