Central Board of Film Certification ( CBFC) chairperson Pahlaj Nihalani watched the trailer of Akshay Kumar's upcoming movie 'Toilet: Ek Prem Katha' and later took to Twitter to praise the premise of the movie.

Nihalani even said that the movie should be tax-free as it promotes Prime Minister's 'Swachh Bharat' Abhiyan.

"Watched trailer of @akshaykumar's #ToiletEkPremKatha. Based on true incidents, it promotes #SwachhBharat.Should be made #TaxFree. #SuperHit!" Nihalani tweeted.

The movie reportedly revolves around Prime Minister's Narendra Modi's 'Swachh Bharat' Abhiyan and campaigns against open defecation. The underlining subject is also believed to highlight the importance of the pay-and-use toilet scheme. 'Toilet: Ek Prem Katha' is slated to release on August 11.
