Its the Oxo dad!!!!
Have a look at the scene at the start of the film where Sean Connery is walking up the road past the school.
There are two policemen posing as workmen. One is crouching and the other is stood up.
Look carefully at the man standing up it is none other than Michael Redfern who played opposite Lynda Bellingham in the Oxo cube adverts!!!
How's about that then??!!
