Actor Shia LaBeouf makes a short film which borrows word-for-word dialog from a comic by Dan Clowes (author/artist of Ghost World). The film plays at festivals, then someone notices the uncredited rip-off, and Shia makes weird apologies via Twitter. Then he makes an apology in the sky with an airplane, apparently. But all the while there is more plagiarism or borrowing going on. He even borrowed other people's apologies. So is he just a thief, or is there some deeper level of conceptual art gesture here?
