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: Moyer's TV debut came with a regular role in the ITV sitcom Conjugal Rites. He also had a recurring part in miniseries Castles and acclaimed drama The Grand. He also turned up in episodes of Casualty, Waking the Dead, Cadfael, A Touch of Frost, Midsomer Murders and Sunburn. His first film part was the title role in 1997's Prince Valiant. He's since appeared in Quills, Trinity and Perfect. Arguably his biggest British TV role came in NY-LON. He began to get noticed in Hollywood thanks to the miniseries The Starter Wife. He's played vampire Bill in American drama True Blood since 2008, although he's no stranger to televisual vampires having appeared in two episodes of Ultraviolet in 1998.

She went on to have a recurring role in The Royal Today. In 2011, she began playing Sarah Barnaby alongside Neil Dudgeon in Midsomer Murders.

Career: Jones teamed up with a friend to create the comedy double act Clark and Jones, who were very successful on the northern club circuit, and also studied acting at the Manchester School of Theatre. His big break came in 1993, when director Ken Loach cast him in the film Raining Stones. He followed this up with appearances in the TV series Roughnecks, Heartbeat, Band of Gold and A Touch of Frost, and also took roles in the movies Bob's Weekend, TwentyFourSeven and The Full Monty. In 1997, he became a household name when he joined Coronation Street as loudmouth layabout Les Battersby. Since leaving the soap under something of a cloud he has appeared in several reality shows, including Celebrity Wife Swap, Celebrity Come Dine With Me, and Famous, Rich and Homeless. In August 2013, he entered the Celebrity Big Brother house.
