Iain De Caestecker's trade is the clever, frightened young man: the sweat, the apology, the look that says he would rather this were happening to somebody else. He has done it since 2011, and the parts that let him do it are the good ones.
Fi1m perspective
Watch what Iain De Caestecker does with a revelation. In The Fades (2011), as Paul Roberts, the chosen boy of Jack Thorne's six-part horror, he takes each new piece of the supernatural like bad news from a doctor: he sweats, he apologises, and he looks as though he would rather it had happened to somebody else. He gives the genre a reluctant hero, and it makes the shaky opening hour bearable. We were on his side before the plot gave us a reason to be: a boy who keeps saying sorry while the dead gather is easier to believe than one who squares up to them.
He had been acting for a dozen years by then, from a BBC short at nine to two years in Coronation Street (2001–2003). Young James Herriot (2011) and The Fades made him a lead on British television; Shell (2013) put him in a Scottish drama we recommended, though it is Chloe Pirrie's film and our review did not single him out. Then America: six seasons of Marvel's Agents of S.H.I.E.L.D. (2013–2020) as the engineer Leo Fitz, with Lost River (2014), in which Ryan Gosling cast him as Bones for his debut as director, and Overlord (2018) on the side.
He is cast as the clever, ordinary man in a situation that is neither, and what he is good at is the strain of it: the tension in the shoulders, the quick turns from one feeling to the next. It made his Fitz and Elizabeth Henstridge's Simmons the part of S.H.I.E.L.D. people kept talking about, and it carried The Control Room (2022), a thriller built on a man who should not be where he is. His own account of that part says it best: "We tried to show the level of fear and discomfort that told the truth about how much he is not built for that world."
The limit is the same thing from the other side. When a thriller leans on the anxious everyman and nothing else, as some felt The Control Room did, the performance can look like a setting rather than a choice. In the louder genre films, Overlord especially, he is competent and not much remarked on. The Winter King (2023), with him as Arthur Pendragon, is the test: a mythic lead played at human scale, quieter and stiller than the boy in The Fades, with the stillness doing the work the fright used to do.
He came back to Britain after six seasons in the sun, by his own telling because it did not feel like home. The work since suggests the same instinct: smaller rooms, colder weather, parts where the frightened man is the point and not the comic relief. If a studio offers him another engineer, we hope he looks at the script the way Paul looked at the dead.
