Graham Ashley

Graham Ashley (26 April 1927-30 October 1979) played the Overseer in the Doctor Who story The Underwater Menace.

One of his most famous roles was in Episode IV of Star Wars.

He is perhaps best remembered as the bad-tempered school caretaker Mr. 'Grumpy' Garfield in the first three seasons of the children's school drama series Grange Hill (1978-2008), who was the very first character to appear on-screen in the opening episode.
