DOHA (AFP) - Qatar opened on Tuesday its annual Doha Tribeca Film Festival with Black Gold, a movie by French director Jacques Annaud partly shot in the gas-rich Gulf country. Starring Antonio Banderas and Freida Pinto, Black Gold tells the story of two emirs locked in a feud after the discovery of oil, as a young leader emerges to unite the desert tribes. Omar Sherif and Lebanese director Nadine Labaki were on the red carpet for the opening as well as Pinto. US actor and the founder of New Yorks Tribeca Film Festival, Robert De Niro, helped to organise the first Doha festival in 2009. New Yorks Tribeca Film Festival was launched to boost cultural life in Manhattan after the September 11, 2001 terror attacks.
