Controversy dominated the Venice Film Festival, with two directors arguing about their work, one saying the other should go to hell.Bad Lieutenant – Port of Call New Orleans re-visits the corrupt cop role made famous by Harvey Keitel 17 years ago. This time, the lead is played by Nicholas Cage although director Werner Herzog insists his film has nothing to do with Abel Ferrara’s 1992 work, and he is just happy to be in Venice. “It is the first time that I’m in competition. The festival never accepted one of my films in competition before, so I’m very proud,” said Herzog. Herzog’s new movie has Cage as a drug-addicted policeman protecting his prostitute girlfriend, played by Eva Mendes, as he hunts a drug dealer suspected of murder. The film was shot in the aftermath of Hurricane Katrina, and portrays the corruption of authority through Cage’s excesses and organised crime moving in on redevelopment projects.
