Niall had a small role in Zack Snyder‘s 2009 film “Watchmen”. He portrayed Byron Lewis, also know as Mothman, one of the Minute Men featured in the films flashbacks.
“Watchmen” was an ambitious project, based on the DC Comics series of the same name by Alan Moore and Dave Gibbons. A dark take on the superhero genre, it is set in an alternative 1985, telling the story of a group of retired superheroes following the outlawing of masked vigilante groups. The murder of one of their own leads to their uncovering a deadly conspiracy.
Niall’s character Mothman features in flashbacks in the movie, as the story of a previous group of superheroes, known as the Minute Men, is told linking the past to the present. He also features in a mock documentary released with the DVD of the film, entitled “Under the Hood”.
