Check out Green Day’s poignant new video for ”Wake Me Up When September Ends.” The seven-minute epic features actress-of-the-moment Evan Rachel Wood and Jamie Bell (left, of Billy Elliot fame) as teenage lovers wrenchingly separated when he enlists in the military and goes off to fight in Iraq. Samuel Bayer, who has directed all of Green Day’s recent videos (and, incidentally, the pep-rally-from-hell clip for Nirvana’s “Smells Like Teen Spirit”), tells MTV News that ”September” is the best thing he’s ever done — and it’s hard to argue.
