John Hamill is an English actor.

He had previously been a bodybuilder and one of England's most popular "physique models" in the late 1960s before turning to acting, studying at the Webber Douglas Academy of Dramatic Art, and appearing in the stage farce There's a Girl in My Soup.

Hamill’s background as a physiques model, which included cover appearances on several beefcake publications and the occasional 8 mm ‘posing strap’ film, earned him a considerable gay following, which is still visible on the internet today. It would also prove good training for his later nude appearances in David Grant’s sex films and nudity ridden horror titles like Tower of Evil (1972), in which Hamill’s role in synopsized by The Bare Facts Video Guide as “Buns, walking with Penny, then more buns, rolling into the water, dead”.

He left acting in the late eighties, and went on to run a pine furniture shop. His last known TV appearance was in an episode of The Bill in 1989.

He also appeared in the following films: Trog (1970), No Blade of Grass (1970), Travels with My Aunt (1972) and Hardcore (1977).

Television appearances included: Crossroads, Space: 1999, The Venturers, 1990, Doctor Who (in the serial The Ribos Operation) and The Professionals.

Jimmy Gardner had two roles in Doctor Who. In 1964 he played the role of Chenchu, the manager of the way station at Tun-Huang, in the fourth story of the series Marco Polo. He returned to the series in 1978 to play the role of Idmon in the fourth Doctor story Underworld. Idmon was a Trog on the planet formed around the P7E, and the father of Idas. He tried to encourage the other Trogs to rebel, but was arrested by the Guards and selected for sacrifice. He was rescued by the Doctor and escaped his planet's destruction on board the R1C.

Gardner had a long eventful life. He was a war hero, a survivor of two shipwrecks and numerous escapades on land, and was awarded the Distinguished Flying Medal after completing some 30 missions as a Halifax rear gunner in No 10 Squadron. After the war he trained as an actor at The Central School and had a long career in television, film and stage. He appeared in many classic TV series including The Forsyte Saga, The Lion, the Witch and the Wardrobe, Dixon of Dock Green, Z Cars and The Onedin Line. In film he worked on Robin Hood: Prince of Thieves and had his most notorious role as Ernie the bus driver in Harry Potter and the Prisoner of Azkaban.

Anthony Ainley was an English actor best known his role as the Master in Doctor Who.

He was born in Stanmore, Middlesex, the illegitimate son of the actor Henry Ainley(1879-1945) and Clarice Holmes. Known as Tony, he was brought up in the Actors Orphanage alongside his elder brother Timothy, but showed little interest in acting at an early age, with his first career instead being as an insurance clerk. He also showed a keen interest in sports, engaging in rugby and - his major passion in life - cricket.

He adopted his father's surname when his interest in acting grew (perhaps to raise awareness of himself through his that respected name). Having graduated from RADA, he had an early regular role as Det. Sgt Hunter, sidekick to William Mervyn's Chief Inspector Rose in the second series of It's Cold Outside in 1966. Other notable roles include a subaltern in the 1969 film version of Oh! What a Lovely War, Dietz in the 1975 film version of The Land That Time Forgot, Fallowfield in the Tigon film Blood on Satan's Claw (1971), Henry Sidney in Elizabeth R (1971), Clive Hawksworth in Spyder's Web (1972), Rev. Emilius in the BBC's adaptation of The Pallisers (1974), Johnson in the first episode of the BBC programme Secret Army (1977), and Sunley in The Avengers episode "Noon Doomsday" (1968). He was also one of the Hong Kong policemen who discover James Bond's supposed corpse in the opening sequence of You Only Live Twice (1967).

Ainley played the role of the wealthy young peer Lord Charles Gilmour in the ITV series Upstairs, Downstairs (1973).

Reportedly, it was his performance as Rev. Emilius (in The Pallisers) that led to him being offered the role of the Master by John Nathan-Turner, who had worked on The Pallisers seven years before becoming producer of Doctor Who.

Ainley first appeared in The Keeper of Traken alongside Tom Baker - the two got on well as the latter was a friend of his half-brother Richard Ainley(1910-1967, also an actor). Becoming the Master at the end of that story, he went on to reprise the role in some nine further adventures, appearing at least once in every series to 1986, and in the very last story of the series' original run, Survival in 1989. He returned to the role once more to provide the links for the1997 BBC computer game Destiny Of the Doctors.

By the 1980s he had effectively retired from acting, except for his occasional Doctor Who appearance, living on private means. Instead, he continued to engage in his love of cricket right up until his death in 2004.
