HBO Documentary Films has acquired U.S. broadcast rights to Me @ The Zoo, which will appear in the U.S. Documentary competition at this month’s Sundance Film Festival. The feature doc, directed by first-time helmers Chris Moukarbel and Valerie Veatch, explores Internet celebrity and focuses on video blogger Chris Crocker, whose “Leave Britney Alone” post on YouTube made him a Web star. Submarine’s Josh Braun negotiated the deal with HBO; Memento Films International is handling international rights.
