Oscar-winning actor Christoph Waltz was left shaken after a French television interview at the Cannes Film Festival was interrupted by gunfire.

The drama unfolded when the Django Unchained actor was being interviewed for France's Le Grand Journal at the Cannes Film Festival on Friday (May 17) when gunfire was heard.

Speaking to the Daily Mail, Waltz said: ''I was on a panel at the Studio Canal platform off the beach when a man produced a gun. I think it was a pistol and he fired but luckily for me they were blanks.

''Then he shouted he had a grenade and again luckily for me there was no grenade.

''The police have him. They tackled him to the ground. I don't know who he was or where he came from or what his problem was.''

The male suspect was arrested at the scene and police discovered he was carrying a fake grenade and a knife.

No injuries were reported and the telecast resumed a few minutes later.

 

This incident follows a jewellery heist on Thursday (May 16) at the festival during which an esitmated $1million worth of Chopard gems where stolen from Novotel Suites in Cannes.
