I walked into Universal Studios behind this guy - his back to front baseball cap conveyed an amusing message (Disney brand - "BEING GRUMPY ROCKS"), but unfortunately I had forgotten to turn the artistic filter off on my camera that I'd been playing around with.
These people were hanging around the not quite open yet Diagon Alley area, which I have yet to visit. It all looked very exciting.
Another camera filter - only showing yellow!
I'm not sure who this man was meant to be - Robocop?
