Mick Dillon was born into a horse-racing family; his grandfather, a native of County Kerry, was an near-legendary trainer of racing champions; Mick's father and uncles were top notch jockeys on racecourses in England and elsewhere; Mick's uncle Bernard Dillon was briefly married to the music hall diva Marie Lloyd. With such a family history, it was natural that Mick would soon find himself on a horse, as he was, riding in races from a very early age. Although he appeared in a few movies and television programs, Mick was best known as a stunt double appearing for such actors as Buster Keaton in A Funny Thing Happened On The Way To The Forum (1966), Ringo Starr in Help! (1965) and David Hemmings in The Charge of the Light Brigade (1968); he also appeared as the monster in Gorgo! (1961), a Dalek in Dr Who & The Daleks (1965)and as a Triffid in Day of the Triffids (1963).
