Matt Smith (Actor) .. The Doctor

Born: October 28, 1982 in Northampton

Best Known For: Being the current Doctor Who.

Early-life: Matthew Robert Smith was born on October 28, 1982, in Northampton. A promising footballer from a young age, he played for the youth teams at Northampton Town, Nottingham Forest and Leicester City. He looked set for a professional career until a back injury scuppered his chances. A teacher encouraged him to act, and although reluctant at first, he eventually joined the National Youth Theatre. He also studied drama and creative writing at the University of East Anglia. At the same time, his professional stage career began to take off, and he was allowed to miss lectures during his final year so that he could work.

Career: Smith's first professional roles came in the plays Fresh Kills, opposite Christian Slater, and On the Shore of the Wide World. He appeared with Slater again in Swimming with Sharks, and also featured in The History Boys. He was part of the Olivier Award-nominated cast of That Face. His TV roles include The Ruby in the Smoke, The Shadow in the North and Secret Diary of a Call Girl, all alongside ex-Doctor Who assistant Billie Piper. He also starred in political drama Party Animals, and made his debut as the 11th Doctor Who in 2010. He was the youngest actor to play the part, but will bow out at Christmas, when he'll be replaced by Peter Capaldi. Other projects include Christopher and His Kind, Bert and Dickie, Womb, and the forthcoming How to Catch a Monster. He will return to the West End stage in 2014 to play the lead in a musical version of American Psycho.

Quote: 'I'm tired of television that's patronising and silly. I think Doctor Who is brave and it's inviting, challenging. For me anyway; I can only speak personally.'

Trivia: He's a Blackburn Rovers supporter and loves the band Radiohead.

Karen Gillan (Actor) .. Amy Pond

Career: Gillan's early TV career included guest appearances in Rebus, Harley Street and Coming Up. She played various characters in The Kevin Bishop Show.

She made appearances in the show as Amy until 2013. She has also starred in the TV movie We'll Take Manhattan and the film Guardians of the Galaxy (2014). In 2014, she also starred in short-lived American sitcom Selfie. In 2011, she made her stage debut in Inadmissible Evidence at the Donmar Warehouse.

Many of his early roles came on stage, including in an acclaimed production of Terre Haute at the Edinburgh Festival Fringe. He worked with future Doctor Who co-star Matt Smith in Swimming with Sharks in 2007. A year later, he made his TV debut in He Kills Coppers and followed it with Little Dorrit, but it was travelling with the Time Lord as Rory Williams that made him a star. Other projects since include the films Sex & Drugs & Rock & Roll, and Robin Hood.

Quote: On leaving Doctor Who: 'I'm really going to miss the people. Me, Matt and Karen are still in touch, so we're going to see each other whenever we can, but it's different when you're not working together any more. Brilliant, brilliant actors - we know each other so well. We'll still chat.'

Her parents divorced when she was nine. She has a brother, Luke, who's a cameraman, and two half-brothers from her father's second marriage to actress Kika Markham. Redgrave claims her childhood home was always full of her mother's friends, some of whom she didn't like. The open house nature of her upbringing made her long for discipline and structure.

Since then she's appeared in such projects as I'll Be There, The Grid, Amnesia, Tom Brown's Schooldays, Frankie and Doctor Who (including the 50th anniversary episode). Redgrave also continues to work on stage.
