COMPO! Appear In Doctor Who!

Win the chance to appear alongside William Hartnell in vintage Doctor Who episodes!

It’s a longstanding joke that the BBC has every single Trooping The Colour in the archive, but numerous episodes of Doctor Who are missing. It’s unlikely, however, that anyone would go back to animate any absent moments from the Queen’s annual birthday shindig.

French Revolution-set William Hartnell serial “The Reign Of Terror”, of which two out of six episodes have been lost in time, is the latest Who story to get the holes filled in with animation. “It’s a bloody good story!” says producer/director Austen Atkinson, from aptly named production outfit Theta-Sigma. “It’s also beautiful, and we think the incredible detail we put into our backgrounds will lend itself well to the sumptuous costume drama – which is what this is, really.”

Atkinson describes the style as “traditional 2D animation”, and says that his team has had very little material on which to base their reconstruction. “We’ve got the camera scripts, some set photos, we have the audio track, and we have the existing episodes, but very little else,” Atkinson admits, adding that he called in the University of Paris’s archaeology department to help make the restoration’s vision of France look accurate. “It’s very clear to me that this is an archival exercise like taking a wonderful painting off the wall and restoring it. We’re treating it like it’s a holy grail.”
