Career: Playing mainly minor roles, Capaldi went on to feature in episodes of Minder, C.A.T.S. Eyes, The Lair of the White Worm, Rab C Nesbitt, Ruth Rendell Mysteries, Agatha Christie's Poirot and the miniseries Selling Hitler. He returned to the big screen when he wrote and starred in 1993's low-budget Soft Top Hard Shoulder. Guest starring roles followed in Prime Suspect 3, The Vicar of Dibley, Judge John Deed, My Family and Midsomer Murders. His profile raised significantly in 2005 when he began playing foul-mouthed spin doctor Malcolm Tucker in BBC comedy The Thick of It, a role that won him a Bafta. He also played Tucker in movie spin-off In the Loop. Always in-demand, his other TV credits include Skins, Torchwood: Children of Earth, The Nativity, Getting On and The Hour.

Career: Coleman went on to have a recurring role in Waterloo Road, but claims that playing a schoolgirl at the age of 23 was 'surreal'. She went on to appear in Julian Fellowes' ITV mini-series Titanic and starred in a BBC Four adaptation of John Braine's novel Room at the Top. She made her film debut in Captain America: The First Avenger (2011). Her profile increased significantly in 2012 when it was announced that she would play the companion in Doctor Who. Away from the sci-fi drama, she has starred in Stephen Poliakoff's Dancing on the Edge and the three-part drama Death Comes to Pemberley. In 2013 she dropped 'Louise' from her name and is now known as Jenna Coleman.

Career: Kaye got his TV break working on BBC Two's Sunday Show when he was 24, playing Dennis Pennis, a character he invented during evenings out with his friends, never expecting anything to come of it. Despite being a cult hit, Kaye decided to quit playing him when he found it difficult to get interviews with stars. Away from Pennis, he's appeared in comedy series Perfect World and Citizen Kaye, and hosted game show Liar. He has also starred in It's All Gone Pete Tong, Two Thousand Acres of Sky, Kingdom, Skins, Mongrels, Shameless and Being Human.
