Tom Baker, who starred in "Doctor Who" from 1974 to 1981, is returning to the BBC's cult television series in a cameo role in a completed version of an episode that was never finished, the New Musical Express reported.

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.
