Film security men show remarkable patience with an inebriated man who insists on singing and holds up the filming of a scene from the new Sir Michael Caine film, A NIGHT IN HATTON GARDEN. The delayed scene involved actor Charlie Cox peering out from a door , and the multi million pound production was held up for approximately twenty minutes ! Eventually, the security had to threaten that they would call the police ,and the man wisely wandered off into the night, soon afterwards. The film is based on the true story of how an elderly gang of villians broke into a security vault in the Hatton Garden area of London and stole hundreds of millions of pounds worth of gems from individual security boxes.The movie also stars Ray Winstone ,and it is said Sir Michael Gambon,Francesca Annis,and Sir Tom Courtney are also involved .
