Um... nothing to do wtih Donnie Darko, I just couldn't think of a better title. You might have seen/heard about the stage version of His Dark Materials at the National Theatre (on again this winter). I loved it, but thought the bear costume/masks could have been improved. This is, approximately, how I would have outfitted the actors. The model is based on a little wooden artist's maquette and the materials are sheet foam, wire, paint, tracing paper and bits of Sainsbury carrier bags.
