Essentially - The Smugglers and The Underwater Menace will be animated and colorised for the 60th anniversary. They're also expected to colorise An Unearthly Child. Funding for the animated episodes has been found, and it apparently has nothing to do with Disney.
Very random choice of episodes but still pretty welcome! I have a feeling they'll do The Celestial Toymaker this year as well, given what's predicted for the anniversary.
EDIT: With The Smugglers being animated, it leaves only The Highlanders from season 4 without an original recording/animation.
For Hartnell, only 6 serials (27 episodes) remain missing with no official recon/animation.
For Troughton, only 3 serials (13 episodes) have no official recon/animation.
