By Charles Webb "He knows what he wants - he says 'This is how we're going to do the scene,' and we'll often just do it in one take." Muyzer, whose VFX company has worked alongside Blomkamp since his feature debut, "District 9," and spent four years developing the dystopian action film "Elyisum," says this approach is "scary for the people behind the scenes," but Blomkamp's approach allows him to sidestep studio and screening notes: there are no backup shots or cuts, only what the director has put on the screen. "Elysium," which is out this week on home video, follows Matt Damon's character Max, a factory worker who suffers a lethal dose of radiation poisoning, and must get to the orbiting city of Elysium in order to be cured.
