UPDATE: According to reports, Shia LaBeouf also plagiarized his apology. wasn’t exactly a new thing. The Shia LaBeouf-directed short premiered at the Cannes Film Festival Critic’s Week sidebar in 2012, and, despite some acclaim, little was made of his portrait of an online film critic.

But the film was made available online Monday, and things started to spiral out of control quickly when bloggers noticed that LaBeouf’s short film bore a striking resemblance to author Daniel Clowes’ comic Justin M. Damiano. Soon after, articles started dissecting the similarities and direct references to Clowes’ text without any attribution, and the video disappeared behind a password-protected wall.

LaBeouf had remained out of touch for most of the day, and his reps did not immediately respond to EW’s request for comment. But then, early Tuesday morning, LaBeouf decided to tweet his thoughts on the kerfuffle, culminating in the mea culpa, “I f—-d up.” Take a look after the jump.

EW’s request for comment to Clowes was not returned.

But the controversy doesn’t end there. Buzzfeed points out that part of LaBeouf’s apology comes from an answer from a user named Lili on Yahoo Answers.
