Series: Lost episodes found after 45 years unseen! Patrick Troughton's 1968 BBC Time Lord arc looks astonishing on DVD. Five of its six Yeti/Brigadier episodes were unearthed on film at a Nigerian TV relay station, then VidFire-processed to restore their original videotape sheen. (Episode 3 uses stills over full-length audio.) The story's action picks up from the also-rediscovered Troughton double-role tale "The Enemy of the World," due on disc May 20. (Both dropped at iTunes last fall.)

Extras: Nothing. Not even an account of the Nigerian find.

List price: $20, out April 22 from BBC.
