The BBC have named the latest recruits to Torchwood, the forthcoming Doctor Who spin-off series.
Burn Gorman and Naoko Mori will join previously announced cast members John Barrowman and Eve Myles.
Gorman plays Owen Harper “the raw but charming medic of the group”.
Mori plays Toshiko Sato, a role she first played in last year’s Aliens of London.
Sato is described as “the member of the team who specialises in all things computer, surveillance and technical”.
Of Naoko, Russell T Davies says: “We were lucky enough to work with Naoko in 2004, on the very first day’s filming of the new Doctor Who, which introduced the character of Toshiko Sato in the episode Aliens of London.
“She was absolutely brilliant, and I knew then that I wanted to bring her back.”
The 13-part series begins filming in Wales next month and will transmit on BBC THREE and BBC ONE.
