Jodie Whittaker played the 13th Doctor on "Doctor Who."

She is the first woman to play the role of the titular Time Lord.

The show first premiered in 1963.

Whittaker already knows who she wants her replacement to be.

She thinks that Lydia West would be a good pick.

Lydia West, 28, is a Black British actress.

She made a splash in the BBC series "Years & Years."

She also starred in the HBO series "It's A Sin."

BBC has yet to announce who will take their turn in the TARDIS next.
