Blink and you would've missed Nicholas Hoult's entrance at the Mad Max: Fury Road international press conference in Los Angeles recently.
It's really a reflection of his boy-next-door personality. The English actor played the geeky mutant Beast in last year's X-Men: Days Of Future Past, and a good-looking zombie in 2013's Warm Bodies.
In person, the 28-year-old is charming in an unassuming fashion - a far cry from his role as a fervent soldier in the fourth Mad Max movie.
George Miller's high-velocity film sees the English actor in a role that's anything but subtle.
In the film, Hoult plays War Boy Nux who has a cult-like devotion to the film's villain, Immortan Joe. Nux lives a fairly miserable existence as a driver with a V-8 engine block scarified on his chest.
"He doesn't know much about the world. All he knows is that he's got only a half-life. He's got these tumours on his neck called Larry and Barry, who are kind of his pals, but are also killing him," says Hoult.
"His relative innocence and enthusiasm are what set Nux onto the path he takes in this film," he adds. If anything, Nux's journey is a live wire one. His character is one that mirrors Miller's psychotic apocalyptic premise.
Nux is bold and unpredictable, and the first half of the movie sees him channelling "Mad" Max Rockatansky's blood into his body via an intravenous tube while speeding across the desert.
Of this rather crazy scene, Hoult says: "Max is terrified and miserable, and that's sort of hilarious to Nux. He's having the time of his life."
