Being Human is to lose another major cast member with Russell Tovey announcing that he too is bidding farewell to the show.

Tovey confirmed the news via his Twitter: “Hey my lovely witty’s, you may or may not know by now, but I am leaving Being Human officially. Thought you should all know… I’m sorry.”

Tovey gave some possible clues as to why he is leaving to The Guardian: “Aidan [Turner’s] left to film The Hobbit in New Zealand [with Peter Jackson] and going on without him on this fourth series felt strange.”

Despite losing two of its three original cast, Tovey still thinks the show can continue: “With Being Human the story can definitely go on and on,” Tovey insists. “Toby [Whithouse, the writer] still runs it and they can do all sorts … add giants and robots!”

Tovey will exit the show during the fourth series which is due to air early 2012.
