Re: Who's side are you on?
An old fart like me still fondly remembers 1983, when there were *two* James Bonds (Octopussy and Never Say Never Again). Didn't stop either movie from making boatloads of moolah at the box office. I'll be perfectly happy to watch both versions of Quicksilver, too.
But as far as doing an in-depth and meaningful portrayal of the character, there's no question that Whedon has made it clear that his Pietro has a larger and more important role for TA2 than Singer's Quicksilver cameo.
Dunno why Singer wanted to get into an e-peen pissing contest. Maybe the fanwar will generate more tickets than he was ever going to get otherwise (why hello there, Jack the Giant Slayer, Valkyrie and Superman Returns)
