The Cannes film festival opens tonight, albeit with a slightly subdued feel good factor, due to the credit crunch.The famously extravagant cinema showcase is focussing on the films not the fripperies. Ostentatious elegance takes a back seat this year as Hollywood studios tighten their belts with conspicuous consumption temporarily out of fashion. On the plus side – it’s been a bumper box office year despite the global recession. But slowing DVD sales and depressed advertising has cast a shadow over Cannes. No co-incidence then that the festival’s curtain raiser is the animated Disney film Up. At the other end of the scale Quentin Tarantino’s film Inglourious Basterds tells the fictional tale of a group of Jewish GIs, recruited to take revenge on the Nazis behind the lines in occupied France. The World War Two drama is one of 20 films vying for the coveted Palme d’Or for best picture.
