An online extension of Being Human has been commissioned by the BBC. Becoming Human will follow a new group of characters over nine episodes.

Created by Toby Whithouse (Doctor Who), the spin-off will be written by Brian Dooley (Being Human, The Smoking Room), Jamie Mathieson (Being Human) and John Jackson (Being Human).

Following events that unfold in the forthcoming third series of Being Human, vampire Adam (Craig Roberts) is at college trying to get himself back on the straight and narrow. It’s here he meets the beautiful, cool Christa (Leila Mimmack) – who just happens to be a werewolf. They strike up a friendship with Matt (Josh Brown), and the three of them become embroiled in a mystery that leads to more than they bargained for…

Online audiences will be encouraged to interact with the story as it unfolds, with daily clues and materials posted on a new website linked to the Being Human blog.

Creator Toby Whithouse says: “Yes, because *you* demanded it, the world of Being Human is expanding! We’ve got a cracking story lined up, with some terrific new characters and all the thrills and chills you can manage. I hope you enjoy watching it as much as we’ve enjoyed making it.”

Sarah Clay, BBC Multiplatform Drama Commissioner, says: “The fans of Being Human are incredibly active online, so we wanted to give them something they could really get their teeth into. The Becoming Human online extension doesn’t just consist of nine episodes, the narrative extends beyond that with daily clues in the form of press cuttings, anonymous tips, CCTV footage, mobile phone clips…giving the online audience the chance to follow the mystery on the blog as it unfolds.”

Becoming Human will launch online at bbc.co.uk/beinghuman, midway through transmission of Series 3 of Being Human, which begins on BBC Three in January 2011.
