British television comedian David Jason trained as an electrician, but soon started working in repertory theater, and he landed his first role on television on the soap opera "Crossroads" in 1964. Jason played on the children's television show "Do Not Adjust Your Set" in 1967, and then appeared on several variety programs before getting the role of Edgar Briggs, a clumsy spy on the show "The Top Secret Life of Edgar Briggs" in 1974. Jason continued to play on television before snagging his best-known role in 1981, as money-hungry stockbroker Derek "Del Boy" Trotter on the popular BBC sitcom "Only Fools and Horses," a series which ran until 2003. Jason also made a hit on the bucolic sitcom "The Darling Buds of May" as "Pop" Larkin, father to Mariette (Catherine Zeta-Jones). The series ran from 1991 to 1993. Jason showed a more serious side in the televised World War I-drama "All the King's Men," which co-starred Maggie Smith.
