Name: Daniel Kaluuya
What you know him from: You might recognize Daniel from the Doctor Who episode, Planet of the Dead, where he played one of the trapped bus passengers. Or, you might know him from his brilliantly fun turn on the underrated supernatural series, The Fades, where he played a very Xander-Harris-esque character named Mac.
What do we think his chances are: Pretty good. There's been a huge push to get a black actor in the TARDIS after 50 years of white dudes. Plus. the show's pulled from its past episodes before (Freema Agyeman, Karen Gillen, Colin Baker).
