"Paani" director Shekhar Kapur feels privileged to be working with Hollywood casting director Mary Vernieu, who is one of the favourites of Bollywood directors.

"Great to be working with Mary Vernieu, Hollywood's legendary casting director on 'Paani'. Some of my favourite directors here won't do a film without her," Kapur posted on micro-blogging site Twitter.

Being made under the Yash Raj Films banner, the film will focus on a world where wars break out due to water scarcity. It will star Sushant Singh Rajput in the lead.
