'I'm Not There' an enticing Dylan puzzle

Todd Haynes' film is as full of clues and obscure references as some of the singer's own songs.

HELP! I've followed a rabbit named Todd Haynes down a fantastic aperture, and now I'm having trouble pulling myself out. I'm talking, of course, about "I'm Not There," the filmmaker's fantasia about Bob Dylan. As an avowed Haynes nut (I even own an old bootleg copy of his Barbie-filled tragedy, "The Karen Carpenter Story") and aspiring Dylan know-it-all (I wrote the text panels for the 2004 museum exhibit "Bob Dylan's American Journey"), I'd been waiting a long time to see what he'd do with the Mystery Tramp.
