Career: After stints in local theatre, Jason graduated to TV, joining Michael Palin, Eric Idle and Terry Jones for Do Not Adjust Your Set in 1967. In the early 1970s, he appeared in the films White Cargo and Under Milk Wood and played the lead in TV comedy A Sharp Intake of Breath, before being cast opposite Ronnie Barker in the popular sitcom Open All Hours. He worked with the comedian again in 1975 in Porridge when he played old man Blanco, a performance that prompted producers to invite him to audition for the role of Grandad in Only Fools and Horses in 1981. The show's makers decided to cast him as Del-Boy instead after noticing his obvious chemistry with on-screen brother Nicholas Lyndhurst. It turned him into a household name. In the 1980s, he also provided the voices for animated children's favourites, including Danger Mouse and Count Duckula. Jason's huge success continued in the 1990s with The Darling Buds of May and A Touch of Frost. Even though he retired from the role of Det Insp Jack Frost in 2008, after playing the character for 16 years, he claimed to have no plans to retire himself from acting. His recent work includes The Royal Bodyguard and Still Open All Hours.

Career: Lyndhurst made his TV debut in an adaptation of Heidi in 1974. He followed this with roles in The Prince and the Pauper, and The Tomorrow People. In 1978, Lyndhurst began his transition into more grown-up roles by playing Ronnie Barker's son in Porridge spin-off Going Straight, and classic sitcom Butterflies, but it was Only Fools And Horses that made him a household name when it began in 1981. Since then, he's also starred in The Two of Us, The Piglet Files, David Copperfield, Gulliver's Travels, Goodnight Sweetheart, After You've Gone and Only Fools prequel Rock & Chips. He is now a regular in New Tricks.
