Nila Madhab Panda's directorial "Halkaa", which addresses the problem of poor sanitation in India, has caught the attention of actor Varun Dhawan, who says the absence of sanitation facilities is one of the main reasons for open defecation in India.

Varun said in a statement: "There are street kids whose role Tathastu (child artiste) is playing... As people who want toilet facilities and if it's not there, where they will go - on the rail tracks or open. The film holds a strong message, where a young boy aspires to build a toilet."
