Beastie Boys star Adam Yauch has a bitter taste in his mouth - after bosses at food and drink manufacturer Nestle hit back at his movie which criticized the company's bottled water products.

Yauch screened his documentary film Flow at last weekend's Nantucket Film Festival, claiming the Swiss-based firm is being environmentally irresponsible. The film, distributed by Yauch and his company Oscilloscope Pictures, blames the growing privatization of the world's fresh water supply partly on the company, and others including Pepsi and Coca-Cola.

A source tells the New York Post that Nestle bosses were furious at Yauch after hearing the company's name mentioned, revealing, "She (a company representative) stormed out about an hour in when the film named Nestle. The company obviously had no idea this content was in the movie. She told an audience member, 'That was one-sided,' on her way out and didn't come back for the question and answer session afterwards."

Yauch has refused to apologize for his honestly in the footage. He tells the New York Post, "They (Nestle) put pretty pictures of springs and forests on the bottles, but in this movie they're getting called out. I think it's great. They lock down water as a commodity they can buy and sell. It's terrifying."

Yauch's film is set to debut in New York this September.
