Michael Mann, who last directed Public Enemies, is closing in on his next picture. He’s getting serious about Gold, a contemporary Treasure of the Sierra Madre-type treasure hunt about prospectors and speculators involved in the chase for gold. The project is just taking shape. It had been developed by Paul Haggis, who showed it to Mann as a writing sample for scribes Patrick Massett and John Zinman. Mann liked it so much that he became the director. He’s producing through his Forward Pass banner, with Haggis and his Highway 61 partner Michael Nozik. The hope is to begin production late in the year.

Mann, who has several potential directing projects that include a film about famed war photographer Robert Capa, an adaptation of the 15th century novel Agincourt based on the Bernard Cornwell novel, and Luck. Mann is exec producing that HBO horse racing series and directed the David Milch-penned pilot. The series stars Dustin Hoffman, Nick Nolte, Dennis Farina and Joan Allen. Mann’s repped by CAA.
