QUEER AS FOLK screenwriter RUSSELL T. DAVIES has credited his homosexuality for advancing his career in the entertainment industry, insisting it gave him "an edge" over other writers. The Welshman, who is responsible for spearheading the revival of sci-fi TV series Doctor Who after it was brought back in 2005, doesn't think his homosexuality has hindered his career - and actually believes it was key to his success. He says, "Being gay does make a difference - but that's not a bad thing. It helped me become a writer. When I used to send my scripts in, being gay gave me an edge. "It made me stand out from the thousands of other writers hoping a TV channel would pick up their screenplay. Being different gives you an advantage in most media careers."
