So just a quick thought on why both Fox and Marvel's Quicksilvers have longish hair... because it seems to be annoying a lot of people... most of which seem to be DC Fanboys funnily enough but thats another story. I hold no allegiances and have followed both major comic book brands for years but I just thought I'd weigh in on this one as its already getting silly.
Both companies (Fox and Marvel) have used a longer hair style to add another level of 'finish' to their respective speed effects. We all know that it is the little, almost unnoticeable things within the great effects scenes that leave the audience feeling they have witnessed quality. Its quite obvious that both QS' will have hair that in super-slo-mo will dislplay the raw inertia overpowering gravity as the hair will be whipped back and then back and forth as he darts in and out of the various obstacles within the scene. It will be a very little (some would say inconsequential) thing that if executed will look fantastic.
Oh and ATJ's QS costume from the A:AOU shoot... pretty sure he is simply a guy who has developed unbelievable powers of speed and obviously thought a speed skaters tunic is the obvious choice to reduce drag etc. I would wager that his outfit will be drastically changed and 'professionally' desiged (as in counter-supervillain ops) by the time Coulson (or whomever) gets his chance to design more Super-duds!
