Iain De Caestecker (Leopold "Leo" Fitz) is an established star in the UK, a Scottish actor who quickly made a name for himself in the US. De Caestecker played the male lead in two high-profile BBC series — the BAFTA-winning “Best Drama Series” The Fades, as well as Young James Herriot. The latter of which earned him a nomination for a BAFTA Scotland for Best Actor/Actress – Television.
British psychological horror film In Fear, in which he co-starred opposite Alice Englert, premiered at the 2013 Sundance Film Festival to rave reviews. In that same year he could be seen in feature films Filth, with James McAvoy and Jim Broadbent, and Not Another Happy Ending opposite Karen Gillan. The latter earned him his second BAFTA Scotland nomination, this time in the Best Actor/Actress – Film category.
Upon his first trip to Los Angeles in 2013, De Caestecker landed a series regular role on the much-anticipated Josh Whedon series Marvel's Agents of S.H.I.E.L.D. After a comprehensive search that same year, he was cast in the lead role of Ryan Gosling’s feature directorial debut Lost River with a cast including Saoirse Ronan, Christina Hendricks and Ben Mendelsohn.
In 2017, De Caestecker was cast in J.J. Abrams's supernatural war film Overlord, which is set to be released on 26 October 2018.
