Doctor Who restoration expert defends "experimental" Celestial Toymaker animation

Speaking at a screening of the new animation at BFI Southbank, audio engineer Mark Ayres – who has restored and enhanced the original soundtrack – described the technique as "experimental", and explained that it allows for greater fluidity of on-screen movement.

"This, basically, is all done with motion capture, so they've got actors in to act all the parts along to the soundtrack," said Ayres.

"It's all synchronised to the soundtrack – sometimes it doesn't work and I have to tweak the soundtrack where the dialogue hasn't quite synchronised. But it is a new technique, it is a motion capture technique, and it means the characters are far more fluid."

Ayres acknowledged that the "different" animation style might "divide opinion", but added: "[We've] put an awful lot of hard work into it – I'm proud of it and the animators in Australia, they have really worked hard on this."

The same technique was previously used to animate the missing third episode of 1968 story The Web of Fear, to a mixed reception from fans.

"I know it was very controversial then and they admit it didn't quite work," Ayres said. "It was a trial on a one-off episode, but they've refined it a lot since then.

"It is a new technique, and they've spent an awful lot of time developing the technique and improving it while they've been doing this."

This new version of The Celestial Toymaker – which is available to pre-order on DVD and Blu-ray – will also feature better quality audio than fans have heard previously, with earlier releases having to rely on what Ayres called "a very dodgy recording".

The new recordings, Ayres said, are "much better than we've had before for this story", and were remarkably discovered at a landfill site.

Ayres's work included not just restoration of the existing tapes, but also the addition of new sound effects.

"I have enhanced the soundtrack a lot on this [...] but I've kept it all very in-keeping," he said. "I've tried to be very faithful to the original sound."
