Proof you can tell a science fiction story with only three actors and one, not entirely convincing special effect. Based on the story by Tobias Buckell, who has the story of how it came to be up on his blog. It’s an excellent example of how much you can convey with just a bit of subtle incluing, by working within genre expectations. I can’t be the only one to watch this and be reminded of Ender’s Game, can I?
Some comments: I wonder if the choice of accents for the three actors was deliberate or just a coincidence, but it works in contrasting the boy and his minder with the main character. I’m not sure the premisse of the movie is valid, the reason why it’s young boys/children being sent up there rather than adults, but it makes emotional sense.
