Iain De Caestecker (Leopold "Leo" Fitz) is an emerging star in the UK, a Scottish actor who is quickly making a name for himself in the US. De Caestecker played the male lead in two high-profile BBC series — the recent BAFTA-winning “Best Drama Series” The Fades, as well as Young James Herriot for which he was nominated for a BAFTA Scotland Award for “Best Actor/Actress – Television.” His thriller film In Fear, which he plays the co-lead opposite Alice Englert, recently premiered at the 2013 Sundance Film Festival. He can be seen next in the feature film Filth with James McAvoy and Jim Broadbent. Upon his first trip to Los Angeles, De Caestecker landed a series regular role on the much-anticipated Marvel's Agents of S.H.I.E.L.D. After a comprehensive search, he was cast in the lead role of Ryan Gosling’s feature directorial debut How to Catch a Monster with a cast including Saoirse Ronan, Christina Hendricks and Ben Mendelsohn.
