British actor Sir David Jason was once threatened by a knifeman while filming classic Bbc sitcom Open All Hours.
The star narrowly avoided injury after an attacker lunged at him with a bread knife while he was filming in Doncaster, England during the 1970s.
Jason writes in his autobiography, My Life, "Funny how a certain kind of calm can descend on you in a situation like that. I suddenly looked at this man rather quizzically and said, 'Was there something you wanted?'"
The actor is set to reprise his role as Granville in a one-off Christmas special of the hit comedy in December (13).
