A man arrested at this year's (13) Cannes Film Festival in France for firing a gun during a TV interview with Christoph Waltz has been sentenced to 18 months behind bars. Stephane Cros sparked panic at the movie event in May (13) when he interrupted a beachside interview with Waltz and French star Daniel Auteuil, firing blanks into the crowd and brandishing a dummy grenade. No one was injured in the panic, but the 43 year old has now been slapped with an 18-month jail sentence, according to The Hollywood Reporter. Prosecutor Gwenaelle Ledoigt accused Cros of inciting fear during the scare, likening it to an act of terror: "Using terror and violence to impose his political views, this is the very definition of terrorism. I'm not saying this is an act of terrorism, but intellectually the process is the same, only the degree of violence is different." The Cannes Film Festival was particularly eventful this year (13) - hours after Cros' arrest, it was revealed that a Chopard jewellery collection worth $1 million (£645,000) had been stolen from an employee's hotel room, and a Chinese movie executive behind Keanu Reeves' directorial debut had his luggage swiped. Festival organisers were also duped by a Psy lookalike impersonating the South Korean pop star.
