Another Vampire Diaries standout is headed to the potential spin-off series. Daniel Gillies is set to star opposite Joseph Morgan and Phoebe Tonkin in The Originals, which will be introduced as an upcoming episode of Vampire Diaries that will air April 25, serving as a potential backdoor pilot. All three are reprising their roles from the original series as the spinoff is keeping the three-lead — two vampire brothers and a girl — formula of Vampire Diaries. The only difference is that the female lead, Hayley (Tonkin), is not an ordinary teenager like Vampire Diaries‘ Elena but a werewolf. In addition to his recurring role on Vampire Diaries, which he has played since Season 2, Canadian-born Gillies also stars on the Canadian medical drama Saving Hope. If The Originals goes to series, he will do both shows.
