What's up with that mask Orlando Bloom?!

Orlando Bloom chose to wear a rather unusual Halloween costume Friday night consisting of a rainbow colored mask/hood (?) that looked pretty strange on him. The actor helped to hand out candy at a friend's house in Beverly Hills before hopping on to his bike (wearing his mask of course) and riding off into the night. As you can see the fans that surrounded Orlando were all wearing much better costumes than Bloom himself!
