New York, Dec 20 (IANS): Microsoft Corporation co-founder Bill Gates has lauded the Bollywood film "Toilet: Ek Prem Katha" and said that it has educated audiences about India's sanitation challenge.

The movie was amongst his seven inspiring things in 2017.

"There's no denying that 2017 was a really tough year... but it also delivered some amazing moments of hope and progress. Here are some inspiring tweets that you may have missed," Gates tweeted on Tuesday.

Later he re-tweeted a link from the Express Tribune and wrote: "'Toilet: A Love Story,' a Bollywood romance about a newly wed couple, educated audiences about India's sanitation challenge."

Directed by Shree Narayan Singh, "Toilet: Ek Prem Katha" revolves around a man named Keshav, who falls in love with Jaya and gets married to her. However, she complains that there is no toilet in the house and he tries to pacify her with temporary arrangements.

Actress Bhumi Pednekar, who stars opposite Akshay Kumar in the film, thanked Bill Gates for recognising our efforts.

"'Toilet: Ek Prem Katha' is our contribution towards ending a practice that affects a very large population of the world. We truly hope open defecation will be a thing of the past. To a brighter and better world. Say no to open defecation," she added.
