A whole host of celebrities, including David Tennant and Billie Piper, were out in force last night for the premiere of the Doctor Who spin-off Torchwood.
The first episode of the action-packed series, starring John Barrowman as hero Captain Jack Harkness, was screened at St David's Hotel, Cardiff Bay, in front of an invited audience.
And Doctor Who himself, Tennant, and Piper, who played his former sidekick Rose, were there to lend moral support.
The stars of Torchwood, Barrowman and Welsh actress Eve Myles, were delighted that so many had turned out for the occasion.
They were joined by Swansea writer Russell T Davies, who wrote both Doctor Who and Torchwood. Both series are produced by BBC Wales.
Myles said it was 'sensational' playing the part of Gwen.
'I've had a very positive reaction to Torchwood,' she said.
'Everyone is extremely excited and complimentary about it all.
'It's a beautiful part to play, there's a beautiful cast and great scripts.'
The evening started with drinks in one of the hotel's plush lounges. Those mingling included BBC Wales controller Menna Richards and Myles's co-stars from the BBC Wales drama Belonging - Richard Mylan and Steve Meo.
The audience was then ushered into an adjoining room for the screening, which was introduced by Ms Richards, who said of Davies, 'His inventiveness and productivity amazes us all.
'Torchwood, I believe, will have as loyal a following as the Doctor himself.'
Ms Richards added that the modern and edgy 13-part series didn't have a 'male voice choir in sight or a miner in sight'.
Sci-fi thriller Torchwood follows a team of modern-day investigators as they use alien technology to solve crime, both alien and human. It will be given its first TV airing on BBC3 on Sunday.
Torchwood has been filmed on location throughout South Wales, including Cardiff Bay, Penarth and at a specially-built studio near Pontypridd. It will be aimed at post-watershed viewers rather than the family audience which typically tunes into the series about the Time Lord. Captain Jack has featured in a number of episodes of Doctor Who.
Davies, who has already amassed awards for Doctor Who, has described his latest creation as 'a British sci-fi paranoid thriller, a cop show with a sense of humour'.
He said, 'It's dark, wild and sexy, it's The X Files meets This Life. It's a stand-alone series for adult audiences which will have its own unique identity.'
Torchwood is fast-paced, sleek and glossy with plenty of dazzling aerial shots of Cardiff. It also has dashes of humour and a storyline to keep even non sci-fi fans interested.
Based in modern-day Cardiff, the Torchwood team delves into the unknown, battling against the impossible in a highly volatile underworld of savage aliens and monsters while trying to maintain their everyday lives.
Captain Jack is the ever-watchful leader of the Torchwood team. He is joined by Ystradgynlais actress Myles, best known for her role as Ceri in Belonging. She plays Gwen Cooper, initially an outsider, who meets Torchwood at the scene of a murder sparking a burning curiosity to get to the truth.
In the opening episode, viewers will see how Gwen tries to get to the bottom of the Torchwood contingent by visiting their secret base underneath Cardiff's Wales Millennium Centre. She embarks on a roller-coaster adventure which includes coming face-to-face with aliens for the first time.
Other storylines include the tale of an alien addicted to sex let loose on Cardiff's nightlife, leaving a trail of gruesome deaths.
- The first two episodes of Torchwood are on BBC3 on Sunday at 9pm and 9.50pm. The first episode is repeated on BBC2 on October 25 from 9pm
