Career: His success as a stand-up was crowned when he won an award at the Edinburgh Fringe Festival. He came to the attention of TV bosses after a stint on the radio. Lee was cast in The Sketch show alongside long-term collaborator Tim Vine. After a short-lived stint presenting They Think It's All Over, Mack and Vine began work on Not Going Out. The series revolves around two friends with opposite backgrounds and personalities, much like the two comics themselves. Mack has recently become a regular on comedy panel shows such as Would I Lie to You? and Have I Got News for You. He also has sell-out tours and best-selling DVDs to his name.

Career: Vine burst onto the stand-up circuit by winning the Perrier Best Newcomer Award for The Tim Vine Fiasco at the Edinburgh Festival in 1995. Tim's solo shows in Edinburgh include Tim Vine Flat Out, I'm Vine Thanks, Tim Vine and the Minotaur, Punslinger and Joke-amotive. He was in both series of ITV's The Sketch Show and appeared alongside his friend Lee Mack in five series of BBC One sitcom No Going Out. They also took part in Let's Play Darts for Comic Relief, with Vine finishing runner-up to competition winner Mack. He's acted in Blandings and is a resident comedian on Celebrity Squares alongside Joe Wilkinson.

Career: Bretton has starred in a number of TV shows, including Sunburn, The Office, Night & Day, Absolute Power, Blessed, and Green Wing, but she is better known for playing Lee Mack's love interest Lucy in the BBC comedy Not Going Out. Her film credits include Outlaw (2007).

Career: Hart did a stint at the Edinburgh Festival and unsuccessfully tried to pitch a show to BBC executives in 2004. It was attended by Jennifer Saunders who loved her performance so much, she cast her in both French & Saunders and Absolutely Fabulous. Hart also had roles as various characters in sketch show Smack the Pony, and starred in BBC Three's Hyperdrive alongside Nick Frost, which was met with an indifferent response from critics. She was then cast as clumsy cleaner Barbara in Lee Mack's Not Going Out and as 'Tall Karen' in 2007's Monday Monday. After gaining further success with radio shows, she was given her own eponymous series by the BBC. It was to prove a hit with viewers who liked its retro and family-friendly style. She's also enjoyed dramatic acting success with Call the Midwife.

Career: West's big break on the small screen came in 1975 when he played the title role in Edward the Seventh.
