i know this is a long shot but i have 2 suggestions,
1) micheal j fox - this guy is the coolest man on the planet! i don't think anyone else could pull off sliding over the bonnet of a car quite like he could! and the man has such fantastic movies under his belt, teen wolf, back to the future trilogy, the hard way, the frighteners, etc.... you know it makes sense!
and secondly, wait for it............
2) george a romero - how awesome would that be?! having the pioneer of the zombie genre at the lfacc! obviously, he probably wouldn't be able to make it this year, what with 'land of the dead' but you should definitely try and snap him up before he starts work on 'diamond dead'. or, as a backup option....... tom savini! the man is also a legend!
who's with me?!
