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: While awaiting his big break, Pertwee trained as an animator and designed album covers. He worked with the Royal Shakespeare Company and made his film debut with a brief role in 1987's Prick Up Your Ears. His appearances in such projects as Blue Juice, Stiff Upper Lips, Cadfael, Cleopatra, Event Horizon, The 51st State and Dog Soldiers turned him into a heart-throb. He was co-owner of production company Natural Nylon with his friends Ewan McGregor, Jonny Lee Miller, Jude Law and Sadie Frost, until its demise in 2003. A prolific voice-over artist, he's also appeared in The Tudors and the Goal movies. His recent projects include UFO, Alan Partridge: Alpha Papa, Elementary and Gotham.

Career: Following a spell with the Royal Shakespeare Company, Parker made his TV debut in 1988's Piece of Cake. He has worked constantly ever since, including a four-year stint abroad during which he appeared in Hollywood films Hamlet and The Bodyguard, although he didn't become a well-known face until ITV's 1998 adaptation of Thomas Hardy's Far from the Madding Crowd. Since then he's starred in the BBC's Vanity Fair, and took over from John Hannah in McCallum. Other notable projects include Othello (directed by his brother), Wide Sargasso Sea, The Haunted Mansion, The Inspector Lynley Mysteries and Stardust. More recently, he has starred in Merlin.
