While you're waiting for the imminent return of Torchwood, there is an awful lot of John Barrowman on BBC America right now. Any Dream Will Do is a reality competition for aspiring West End actors/singers trying to land the lead in a new London production of Joseph and The Amazing Technicolor Dreamcoat. The host is a somewhat subdued (compared to his late night show) Graham Norton. The judges include Lord Andrew Lloyd Webber himself and your very own Captain Jack Harkness. Whether or not musical theater reality competitions are your cup of tea, one episode of this show will leave you wondering, "How does the BBC find a dozen talented singers in the UK, while American Idol can only produce one in a much larger country?" BBC America has packaged the reality show premiere with a one-hour special, John Barrowman: The Making of Me, in which John explores the latest research on the origins of homosexuality and relates it to his own experience growing up. [Related from DISCOVER: Is There a Gay Gene?] Science-wise, the show is sort of a mishmash of different research from fMRI's to the psychology of childhood gender roles to neuroscience, but is redeemed by Barrowman's winning personality.
