In 2070 the Doctor and his travelling companions Jamie (Frazer Hines), Polly (Anneke Wills) and Ben (Michael Craze) arrive on the Moon and set out to visit the Moonbase, a manned structure used to control the Earth's weather through a device known as the Gravitron. All is not well on the Moonbase, however, with many of its crew suffering from a mysterious virus.

I'm like 1,995 years too young for the part, really! No, I think he's going to be quite happy to look his age at last! ... They are just one, but they're all of those actors, and they're all a delight, I think they're all fabulous, and I'm lucky to have them in my DNA, because I've watched it from year dot, so they're great.

The Doctor Who team have kindly donated an incredible once in a lifetime experience. The lucky winner and one other will go behind the scenes of the filming for the first episode of the new Doctor Who series, and will be amongst the first to watch Peter Capaldi as the new Doctor!

We’re very pleased to announce that today is the day we’re beginning the release of our 50th anniversary Doctor Who story The Light at the End. We’re beginning with the Limited Edition CD box set.

It's the 23rd of October, one month ahead of the anniversary of Doctor Who on the 23rd of November, and as of today, the digital download releases for all versions of Doctor Who: The Light at the End will be made available. This includes the Limited Edition, the Standard Edition and the Vinyl Edition.

Mailing out of the Limited Edition CD version has begun today.

Nick Briggs, executive producer: ‘The Standard Edition CDs should start to be mailed out this coming Friday, and the Vinyl Edition will start mailing on November 2nd.

‘With the anniversary of Doctor Who imminent,’ continues Nick, ‘and everyone champing at the bit for the celebrations to begin, we thought it only right and proper that our special anniversary full-cast audio should be released a tiny bit early. Our plans for this very nearly went awry when the company responsible for the physical production of our CDs (and LPs!), Key Productions, experienced a series of unforeseeable problems beyond their control. This is what has caused the slight delay on the Standard Edition and the slightly longer delay of the Vinyl Edition. But for all our customers who can access the digital versions of all these releases, they can listen straight away.

‘We know that those customers who favour listening to the CD or the LP rather than downloading a digital version, might find this a little frustrating, but we thought this course of action would benefit the vast majority of our loyal listeners. We offer our sincerest apologies to any customers who find this decision doesn’t suit them, and hope they will understand our reasons for going ahead with the releases now.’

So, for Big Finish Productions, the 50th anniversary has started early. And for any of you who haven't yet ordered your copy of Doctor Who: The Light at the End, it will be on sale at the Dimensions 2013 convention (all tickets now sold) in Newcastle-upon-Tyne, where the Fifth, Sixth, Seventh and Eighth Doctors (Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann) will be making guest appearances.

As you may have seen, the BF Website is back up and running again. But we would ask that if you can possibly wait a few hours to download The Light at the End, please do. The problem we have discovered is that although we have ample bandwidth to support the download of the quantity of data needed (loads of downloads of The Light at the End) another issue has emerged. The problem is being caused by the sheer number of customers visiting the site at the same time. We have to confess that this is the unforeseen circumstance we simply didn't anticipate. It is because the demand is so unprecedentedly huge that we didn't know to check this before releasing. The analogy that's been used to explain this to us is that it's a bit like having one shop assistant and thousands of customers all arriving at once. Our IT people will continuing monitoring the site and will make all efforts to correct any hold-ups as the hours pass. But, as we said, if you can possibly manage to wait to initiate your download, we would very much appreciate your patience. Huge apologies from all of us here at Big Finish.
