In the new science-fiction film Ender's Game, children are the world's best hope for leading an impending fight against alien invaders, largely because they were raised on computer games so their brains are better suited to the demands of computerised warfare.
It was a happy coincidence, though, that the film ended up casting a real-life tech-savvy teenager, Asa Butterfield, as Ender, a bright young boy who rises through the ranks of the military because of his gaming prowess.
Butterfield, 16, is an accomplished actor who has been performing since the age of seven.
His film credits include Martin Scorsese's 2011 fantasy Hugo, in which he played the title role, and 2008's The Boy In The Striped Pyjamas, where his character befriends a boy trapped in a concentration camp.
But Ender's Game, which opens in Singapore this week, is Butterfield's biggest movie to date.
Directed by Gavin Hood, who was behind 2009's X-Men Origins: Wolverine and the 2005 Best Foreign Language Film Oscar winner Tsotsi, it sees him sharing top billing with megastar Harrison Ford.
Ender clashes repeatedly with Ford's character, a military commander, and in one scene gets to yell at the legendary Star Wars and Indiana Jones actor.
He admits that this was pretty cool.
"Yeah, it's Harrison Ford, what more can you say? I was nervous, as anyone would be," he says, revealing that the 71-year-old was deliberately frosty towards him between takes so as not to break character.
