While John Barrowman and Eve Myles willÂ continue in the roles as Jack Harkness and Gwen Cooper, they are set to be joined by a new regular character, Rex Matheson, who is apparently a “CIA agent born to make waves” who also possesses a “wicked” sense of humour.
It seems that there will be another two recurring characters – apparently Oswald Jones is both a convicted murderer and paedophile; meanwhile Esther Katusi, is a young CIA agent “who learns what sheâ€™s really made of only when sheâ€™s forced to”.
These additional roles seem to be important, to the overall series dynamic and storyline, although of course at this stage it is difficult to speculate how things will fit together.
Torchwood Series 4 will be produced by BBC America, BBC Wales and Starz Entertainment, with Russell T Davies and Julie Gardner continuing in their Executive Producer roles.
