Career: Clunes made his TV debut in a 1983 Doctor Who adventure, followed by a regular role in sitcom No Place Like Home. In 1990 he appeared alongside Sean Connery in The Russia House and two years later in the much-maligned comedy Carry On Columbus. He turned to directing again with comedy film Staggered, in which he also starred. Men Behaving Badly made him a household name - but not until original co-star Harry Enfield was replaced by Neil Morrissey and the series moved from ITV to the BBC. He has chalked up a major success for ITV as über-grumpy GP Doc Martin. Clunes has also presented several documentaries, and appeared in such series as William and Mary, A is for Acid, The Town and Reggie Perrin.

Career: Tate's TV career began with small parts in serial dramas Casualty and The Bill, while her comedy talent was nurtured on The Harry Hill Show, Big Train, That Peter Kay Thing and Wild West, a series she made while pregnant. As well as her critically acclaimed comedy series The Catherine Tate Show, she has also appeared in Bleak House, on the West End stage and in the US version of The Office. The comedienne acquired a new set of fans when she became Doctor Who assistant Donna Noble; she reunited with co-star David Tennant in Much Ado About Nothing in London's West End during the summer of 2011.

Career: Imrie's first professional jobs in showbusiness were in the chorus of various pantomimes. Her film and TV debuts came in 1974 in House of Whipcord and Upstairs, Downstairs. She continued to gain small roles in various productions, but her big break occurred when Victoria Wood offered her roles in As Seen on TV in 1985. Since then, she's continued to occasionally work with Wood and won a prestigious Olivier Award in 2006 for her role in Acorn Antiques: The Musical. Her other credits include Oranges Are Not the Only Fruit, Highlander, Gormenghast, Bridget Jones' Diary, Star Wars: Episode One, Doctor Zhivago, Frankenstein, Calendar Girls, Nanny McPhee and St Trinian's (and its sequel). On TV she has also appeared in Kingdom, After You've Gone, Cranford, and the acclaimed one-off drama The Road to Coronation Street.

Career: Watkins has played supporting roles for most of his career. He has made guest appearances in Soldier Soldier, Casualty, The Bill, William and Mary, Life on Mars, and Lewis among many others. In 2011, he began playing store manager Gavin Strong in Sky1 sitcom Trollied. In 2014, he played his first lead role in The Lost Honour of Christopher Jefferies.
