Finale Season 30 Spoilers!!!!!

John Simm will return as the Master in the two special episodes which bring David Tennant's era as the Doctor to a stunning conclusion. There's been speculation about Simm's involvement with the show but we can confirm he'll be back later this year, once again playing the Doctor's deadly nemesis.

Simm first appeared as the Master in Utopia, The Sound of Drums and The Last of the Time Lords. All three episodes were written by Executive Producer and Head Writer Russell T Davies who also wrote his upcoming adventure.

The character debuted in 1971 and on-screen has faced all but the Second and Ninth Doctors. Davies' version of the Master saw him retain his wit and cunning but since Utopia he's been callous and charismatic, sick, psychotic and enormously likeable. In short, everyone's favourite megalomaniac.

At the close of Series Three we saw the Master gunned down by his wife and whilst lying in his enemy's arms, he refused to regenerate. The world believed he had died and the Doctor accepted he was the last of the Time Lords. But this is Doctor Who and you can't keep a good bad guy down!

We've yet to find out how he survived but we can promise we'll be bringing you an exclusive interview with John Simm and some brand new Master material later this year. Stay tuned!

If anyone wants to remain in the dark about the two specials which form the Tenth Doctor's finale, please look away now! Footage from the first of these episodes was screened during the Doctor Who panel at Comic-Con International, 2009, meaning details about the adventure are officially out there!

As we revealed earlier today, the episodes feature the return of John Simm as the Master. The Doctor's fellow Time Lord is sporting a different hair colour in the finale, working a striking, lighter look.

And the Master isn't the only familiar figure returning from Doctor Who's recent past. Executive Producer Russell T Davies, who wrote David Tennant's final episodes, confirmed that Alexandra Moen is back as Lucy Saxon, the character we previously saw in The Sound of Drums and The Last of the Time Lords. Although married to the Master she put a serious dent in their relationship by shooting him but what happened to her after the events of Series Three has remained a mystery, so far...

Russell further explained that footage from the finale screened at Comic-Con included the voice of Timothy Dalton as the Narrator. His exact role in the specials is currently undisclosed but Dalton is, of course, best known for portraying James Bond in The Living Daylights and Licence to Kill.

One of the biggest cheers of the Doctor Who panel occurred when the trailer showed the face of Catherine Tate, last seen playing Donna Noble in Journey's End. Bernard Cribbins, who played her grandfather, Wilf, also features in the trailer which depicts a grim-faced Doctor walking

His time has come: New Doctor Who Matt Smith begins filming with his gorgeous young redheaded assistant

Six months after Matt Smith was unveiled as the new Time Lord, the actor finally began filming scenes for his Doctor Who debut this week.

The 26-year-old actor and the doctor's assistant Karen Gillan, 21, were spotted on location in Cardiff filming their first scenes together.

A sneak peek of the new show, which won't be broadcast on BBC until 2010, gives fans a chance to see the Doctor's new costume.

While departing Doctor David Tennant normally wore a plain brown suit with a long trenchcoat, Matt's uniform is more retro and slightly Science teacher-esque.

The new Doctor's costume is a brown tweed jacket, bow tie, rolled up trousers and black boots.

Karen, who plays Amy Pond, looked more modern in a baggy green jumper, grey tights and Converse baseball boots.

Getting to know you: Karen and Matt chat outside the tardis

Matt and Karen began filming the new series today, which will be broadcast on BBC1 in the Spring.

Arriving on set today, Matt enthused: 'I feel very privileged and proud to be part of this iconic show.

'The scripts are brilliant - I'm excited about the future and all the brilliant adventures I get to go on as the Doctor.'

The show's new writer Stephen Moffatt, who is taking over from Russell T. Davies, is equally enthusiastic.

He said: 'Matt and Karen are going to be incredible, and Doctor Who is going to come alive on Saturday nights in a whole new way.'

Departing David filmed his last scenes of Doctor Who in May, where he was reunited with former assistant Billie Piper, as well as his current helper Catherine Tate.

His final two episodes will be broadcast at Christmas, with viewers seeing David regenerate into Matt.

Matt was announced as the 11th Doctor in January after David announced his decision to depart.

The Northampton-born actor has signed a £600,000 three-year deal, nearly half the amount of David's £1million deal.

Scottish actress Karen was only unveiled as his new companion in May, amid reports ex-EastEnder Michelle Ryan and model Kelly Brook may take the coveted role.

Karen has featured in ITV’s Rebus and hospital drama Harley Street, as well as Channel 4 comedy The Kevin Bishop Show.

The young actress, who is 5ft 11in, has also modelled for designer Allegra Hicks at London Fashion Week.

She briefly appeared in Doctor Who in 2008 appearing as a soothsayer in the episode entitled The Fires of Pompeii.

This time it involves a real-life terrifying high-speed crash - but luckily he walks away from it with cuts and bruises.

The TV favourite, Captain Jack in BBC's Doctor Who offshoot Torchwood, lost control of his turbo-charged rally car in an 80mph smash.

Barrowman was helpless as the £120,000 Subaru PLUMMETED down a verged, FLIPPED over four times and narrowly missed a LAKE at the bottom of the hill.

Paramedics rushed to the scene to pull the shaken 42-year-old from the wreckage. They removed shattered glass from his EYE before he was taken to hospital.

The drama unfolded as Barrowman filmed a race for Channel Five's Fifth Gear in Powys, Wales. The show's presenter, Tiff Needell, 57, sat in the passenger seat.

The crash, screened on the show tomorrow, comes three years after Top Gear's Richard Hammond cheated death when his dragster crashed at 288mph.

Barrowman said: "I'm lucky to walk away unscathed. I got a ticking off from my mum afterwards."

The incident will feature on the next episode of Fifth Gear, which airs tomorrow at 8pm on Five.

Enjoyable: Tiff and John seemed to be having fun before the crash occurred

The pair were lucky to survive the high-speed crash, which saw the car flip over numerous times

Barrowman said: 'I'm lucky to walk away unscathed. I got a ticking off from my mum afterwards.'

Thankfully for his matinee idol looks, the Torchwood star was only left with cuts and bruises and nothing permanent.

The crash will be screened on tomorrow's Fifth Gear, which is shown on Channel 5.

Both men were wearing safety equipment to minimise any possible injuries sustained
