Graham Ashley

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