In its short history the Tribeca Film Festival has been slow to trigger buying sprees and sure enough as the event reached the first weekend's halfway mark no major deals had closed.

However by Saturday interest had coalesced around Keif Davidson's World Documentary Competition entry Kassim The Dream, which recounts the remarkable story of Kassim Ouma, the former Ugandan child soldier who went on to become world junior middleweight boxing champion.

Another popular piece of non-fiction has been This Is Not A Robbery, Lucas Jansen and Adam Kurland's tale of JL Rountree, who was believed to be the world's oldest active bank robber.

Plum Pictures' drama Trucker has generated buzz as well as universal admiration for Michelle Monaghan's turn as an emotionally remote long-haul truck driver struggling to reconnect with her estranged son. New York-based Plum, which is also represented at Tribeca by Bart Got A Room and Life In Flight, expects a deal to close shortly on its Sundance entry Birds In America by Craig Lucas.

Channel 4/More 4 acquired UK television rights to Julie Checkoway's documentary Waiting For Hockney, which received its world premiere at Tribeca last Thursday.

Neal Checkoway and Geralyn White Dreyfous of Littlest Birds and Jana Edelbaum and Rachel Cohen of iDeal Partners produced and Michael Lesser served as executive producer.

Waiting For Hockney follows an eccentric 38-year-old art school graduate who tries to reinvent realism and believes the key to his success hinges on showing his work to his idol Hockney.

'We are thrilled that Channel 4 has embraced this wonderful documentary,' Edelbaum said. 'The struggle to create art and to seek validation for that work is a universal story.'

Cactus Three partner Julie Goldman brokered the deal on behalf of iDeal Partners with Sandra Whipham for Channel 4/More 4.
