New series Orphan Black airs on 30th March on BBC America - the show started life as a creepy conversation between the executive producer Graeme Manson and the co-creator John Fawcett - John commented to Graeme "Wouldn't it be cool if you were standing on a train station and you looked across the tracks and saw yourself, and in that moment your eyes met, and then yourself stepped in front of a train and committed suicide?" (Not sure awesome is what I'd call that, but never mind. . .) Ten years later, and they had a whole TV show where this scenario happens to Sarah (played by Tatiana maslany). She decides to slip into her life and empty the bank account of the deceased lookalike. That's when she discovers that they are actually clones, and that there may be more of them. . .
