TriStar Pictures has entered into negotiations to acquire international distribution rights to the Aussie film “The Silver Brumby,” sources confirmed yesterday.If a deal is completed, it would mark the first time TriStar has taken on an Australian feature and could lead to an ongoing relationship with the pic’s producers. “The Silver Brumby” comes from Media World Features, a Melbourne-based company operated by Colin South and John Tatoulis, and is based on Elyne Mitchell’s novel about a legendary stallion. It headlines Australia’s hottest new actor, Russell Crowe, and Caroline Goodall, recently seen in “Hook,” and co-star with Sylvester Stallone in TriStar’s upcoming “Cliffhanger.” Pic will debut at the American Film Market. Tatoulis, who also directed, says the deal is being finalized with TriStar’s Mike Medavoy and Ken Lemberger by Media World’s attorney Fred Gaines. “The Silver Brumby,” notes Tatoulis, fits nicely with Medavoy’s previous involvement with “The Black Stallion” and “The Bear.” He added TriStar is so impressed with the film’s style and production values that at a recent meeting between Tatoulis and production head Marc Platt, domestic distrib prexy Bill Soady and Medavoy, future projects were discussed for joint development and production. The Aussie Film Finance Corp., which invested $ A3.3 million ($ 2.24 million) in the pic, says it’s delighted at the deal, which is sure to make “Silver Brumby” one of its more profitable ventures. Deal excludes Aussie rights, already taken by Village Roadshow. A summer bow is planned for the U.S.
