One of my favorite character actors since I was a young child, British actor/director Lionel Jeffries, with his bald, egg-shaped head, was fated to play older, often eccentric, men his entire career. In CHITTY CHITTY BANG BANG, he was, in fact, a year younger than Dick van Dyke who played his son but you'd never know it.
As director, his few films include two memorable productions--THE RAILWAY CHILDREN and THE AMAZING MR. BLUNDEN.
