The timey-wimey sci-fi drama announced on Sunday at its Comic-Con@Home panel that Anderson will make his debut in Season 13 as a new character named Vinder.
He joins cast members Jodie Whittaker, Mandip Gill and John Bishop.
The addition of Bishop — a comedian and former footballer whose acting credits include the UK miniseries Fearless and a few episodes of Skins — was announced earlier this year.
“Traveling through space and time alongside the Doctor and Yaz (played by Whittaker and Gill, respectively), he’ll face evil alien races beyond his wildest nightmares.”
