While appearing on The One Show, via ScreenRant, he was asked about Doctor Who. Gatwa said he regretted never getting to face off against the Doctor's most iconic enemies. "I never got to fight a Dalek. A Dalek or a Cyberman," he said.
It would be very easy to cling on to the TARDIS console forever and I fear that if I don't take a deep breath and make the decision to move on now, then I simply never will.
