Lenny Henry Regenerates into David Tennant (TV story)

As a part of Comic Relief 2023, an untitled Doctor Who sketch opened the night's programme. It saw the second live-action appearance of David Tennant as the Fourteenth Doctor, having "regenerated" from Lenny Henry. After the regeneration, the "Fourteenth Doctor", or rather just Tennant in costume, presented the telethon in a regular black and red suit.

Story notes

 * This minisode is a recreation of the regeneration into the Fourteenth Doctor at the end of The Power of the Doctor. Previously, the Dead Ringers sketch Tony Blair Regenerates payed homage to the regeneration into the Tenth Doctor at the end of The Parting of the Ways by having Tony Blair, played by Jon Culshaw, regenerate into a new incarnation played by David Tennant.
 * Lenny Henry previously appeared as a Seventh Doctor in The Lenny Henry Show. Incidentally, that incarnation also appeared to emerge from his regeneration in a new outfit as the Fourteenth Doctor did.

Continuity

 * The Fourteenth Doctor recognises his teeth. (TV: The Power of the Doctor, The Parting of the Ways)
