Actor Ben Mendelsohn has called legendary director Steven Spielberg, whom he worked with on the upcoming sci-fi action movie Ready Player One, a great teacher and a ?really good, good bloke.? Mendelsohn can next be seen playing King Edward VIII to Gary Oldman?s Winston Churchill in Joe Wright?s historical drama Darkest Hour. After toiling away for years as a character actor in his native Australia and elsewhere, Mendelsohn experienced his big American breakthrough playing Pope Cody in the Oscar-nominated drama Animal Kingdom.
