Named executive producer was Russell T Davies, best known as the creator of the controversial Queer as Folk series, but who also was a long-time fan of the franchise; he wrote a novel for the Virgin New Adventures book series, Damaged Goods. Julie Gardner was also named an executive producer on the series. Little was revealed about the proposed series at this point except that it would be a continuation of the 1963-89 series and not a remake.
