Most people these days are familiar with Asa Butterfield as the adorably awkward teen sex educator in Netflix's series "Sex Education," but back in 2013, among many other impressive credits as a child actor, he was in sci-fi film "Ender's Game." In the movie, Butterfield is recruit Ender Wiggin who, with his unusual gift for military training, is chosen to become the next Mazer and lead their army against an alien invasion. Oh, and Butterfield isn't the only name you'll recognise in this movie; the cast is stacked. Expect appearances from Harrison Ford, Ben Kingsley, Viola Davis, Abigail Breslin, and Hailee Steinfeld. Ender and Katniss share the burden of being pretty young for all the leadership that's required of them in their respective wars.
