Joker is a story about an NRI played by Kumar, who assembles a bunch of villagers and camouflages them as aliens so as to get his neglected village Paglapur on the map of India.
"This is the first ever film where such a plotline has been explored. So aren't we different? People claim that they are making different films; I am making one in Joker," said Kunder, whose debut film was also an experimental musical in the form of Jaan-E-Mann.
The director, who is married to ace Bollywood choreographer-director Farah Khan, rues the fact that not many commercial directors are trying to experiment and are just playing safe.
"I am not seeing people taking initiative with a unique subject and then presenting them in full-on commercial format," he said.
Joker also stars Shreyas Talpade, Minisha Lamba, Javed Jaffrey, Asrani, Vindu Dara Singh among others. The film also features an item song by actress Chitrangada Singh.
