Tom Baker to make cameo appearance in lost 'Doctor Who' episode

Baker, 83, will appear in “Shada,” an episode that was left unfinished 38 years ago. Baker starred as the fourth Doctor in the long-running series.

Baker said the Doctor character “probably never left me.”

“That’s why I can’t say away from it, it was a lovely time of my life,” he told the BBC.

“Shada” is available to buy as a digital download and is set for release on DVD and Blu-ray on Dec. 4, the New Musical Express reported.
