1) I actually like the graduation costumes, a damnsight better that either the genuinely horrible Blevins designed ones they got after Doug's death, the Liefeld "costumes", or the strap and pouch laden montronsities of the 90's. Of special note is Doug's flakjacket, an eminently sensible design, and it's notable he was shot a couple of times whilst wearing it and survived, but the first time he didn't... :(
2) The battle in London is a real representation of the original Forbidden Planet comic shop in Denmark Street, it's grown a LOT since then, and moved twice (It's now on Shaftesbury Avenue)
