David Tennant went on to play a certain detective inspector in a quiet seaside town while Christopher Eccleston became John Lennon and Matt Smith earned himself a role in Terminator.
But what happened to the others who lived in (or wrote about) the Tardis? Kathryn Williams finds out Who’s been up to what since they last caught glimpse of the sonic screwdriver.
Karen Gillan (Amy Pond)
After bowing out in the spectacular The Angels Take Manhattan episode of Doctor Who, Gillan hasn’t looked back.
In her final appearance in 2012 as Amy Pond, she was transported to a parallel universe created by evil statues the Weeping Angels in order to be with her beloved husband Rory.
The New York theme continued after her departure as she played 1960s supermodel Jean Shrimpton in We’ll Take Manhattan with Welsh actor Aneurin Barnard.
Gillan’s currently on US television as the vacuous lead Eliza in Selfie and will soon be seen in Marvel film Guardians of the Galaxy, a role for which she completely shaved her head.
She is also in cinemas at the moment, in the spooky mirror film Oculus.
Arthur Darvill (Rory Williams)
Right up until the end of their on-screen relationship in Doctor Who, Darvill’s Rory played second fiddle to Matt Smith’s “Raggedy Man” – but finally in The Angels Take Manhattan, Gillan’s Amy Pond makes the ultimate sacrifice for her husband.
Since disappearing into an alternative New York, Darvill has been most famously seen on-screen in ITV’s successful murder-mystery Broadchurch.
He also appeared in BBC’s The White Queen as Henry Stafford.
And this week he appeared in Radio 4’s play Burning At Both Ends opposite Sean Pertwee, son of the third Doctor Who actor John Pertwee of course. Darvill played wayward The Who drummer Keith Moon and Pertwee played Oliver Reed, with the audio drama exploring the influence of the former on the latter.
Watch the heartbreaking moment the Doctor says goodbye to Rose Tyler:
Billie Piper (Rose Tyler)
Companion to David Tennant’s Doctor, Piper has been a constant television presence since her Doctor Who debut in 2005.
Since “definitely leaving” after two series, Piper’s character returned in series four and for several special episodes including last year’s 50th anniversary specials.
The 32-year-old actress, who is married to Lewis actor Laurence Fox, has appeared in one-off dramas Ruby In The Smoke and A Passionate Woman.
But her most notable television role was as Hannah Baxter in ITV’s Secret Diary of a Call Girl in which she played a high-class prostitute.
She can currently be seen in Sky Atlantic’s horror-thriller Penny Dreadful.

Russell T Davies (writer and executive producer)
Swansea-born Davies is credited with returning Doctor Who to our screens and stayed with the show from its revival in 2005 until he passed into the capable hands of Steven Moffat.
He is also responsible for spin-offs the Sarah Jane Adventures and Torchwood.
Since his departure, Davies has written The Writer’s Tale, a collection of emails between Davies and Radio Times and Doctor Who Magazine journalist Benjamin Cook.
Dubbed the “Great Correspondence” by Davies and Cook, The Writer’s Tale covers a period between February 2007 and March 2008 and explores his writing processes and the development of his scripts for the fourth series of Doctor Who.
Davies was also made an offer from Lucasfilm to work on a proposed Star Wars live-action television series, but he refused the commission.
He has also co-created CBBC’s Wizards Aliens and currently has three connected projects in production including Cucumber, a tale of a group of friends and former gay-rights activists in Manchester and a sister show, Banana, will air on E4 with a connected website.
Noel Clarke (Mickey Smith)
Mickey Smith was introduced as Rose Tyler’s hapless boyfriend at first but soon he was fighting alongside the Doctor as well as any companion before him.
Since leaving, Clarke’s star has continued to soar. He appeared in and wrote the screenplay for Kidulthood and then wrote, directed and starred in the sequel Adulthood, which gained £1,209,319 from the opening weekend of its release. This was after winning the Orange Rising Star Award in 2009.
He has also directed the 2010 crime thriller 4,3,2,1 which starred Emma Roberts. Clarke was last seen in Star Trek: Into Darkness as Thomas Harewood.
Freema Agyeman (Martha Jones)
Agyeman first appeared as David Tennant’s companion Martha in 2007 and continued until midway through series five in 2008, before returning for Tennant’s final episodes the End of Time in 2009.
Since her Doctor Who days she’s been a regular on LawOrder: UK as crown prosecutor Alesha Phillips and up until its recent cancellation Agyeman played Larrisa Loughlin in the Sex and the City prequel The Carrie Diaries.
Agyeman recently joined the cast of the new Netflix original series Sense8. The show, from the makers of The Matrix, is about eight people around the world linked through telepathy. The 10-part series is expected in 2015.
