Green Cross Code

A few years later, having only made one short film, about Dave Prowse - the actor who played Green Cross Code man and provided the on-screen presence of Darth Vader - Yentob hit the big time.

It was good enough for the Green Cross Code man, but lacked the menace of an evil Jedi bent on intergalactic power.

"I am old enough to remember the Tufty Club and the Green Cross Code and the public information films about, 'Clunk Click every trip'," he said.

Prowse was also well known for being the Green Cross Code Man in the 1970s.

Another had a square of white flowers with a green cross, a reference to the Bristol actor's role as the Green Cross Code Man in road safety campaigns.
