ATO Pictures has acquired U.S. rights to Participant Media’s Last Call at the Oasis, the Jessica Yu-directed film that premiered at the 2011 Toronto Film Festival. The documentary is about the global water crisis, the role that water plays in our lives and the hardships that are created around the world when clean water is not available. The film is produced by Elise Pearlstein. The deal was brokered by Submarine’s Josh Braun. It is the second festival film to be acquired by ATO, which bought the comedy The Oranges before the festival wrapped.
