Shia LaBeouf apologized Tuesday after being accused of plagiarism in his short film "HowardCantour.com," which was made available online Monday.

According to CNN, the actor directed the short, which premiered in 2012 at the Cannes Film Festival Critic's Week sidebar in 2012. Despite some positive reviews, little was made of his portrait of an online film critic.

But once the film went public Monday, bloggers noticed LaBeouf's work bore a striking resemblance to author Daniel Clowes' comic "Justin M. Damiano." Articles soon dissected the similarities and direct references to Clowes' text without any attribution, and the video disappeared behind a password-protected wall, according to CNN.

You know what could've got him out of this mess? Another movie about cars turning into robots. People love that stuff. A couple more flying-car-robot-aliens, and suddenly no one is paying attention to short films.

LaBeouf and his reps did not immediately respond to requests from Entertainment Weekly to talk about the film. But LaBeouf tweeted early Tuesday morning, "I (expletive) up."

Well ... that's kind of refreshing.

"Copying isn't particularly creative work," LaBeouf tweeted. "Being inspired by someone else's idea to produce something new and different IS creative work. In my excitement and naiveté as an amateur filmmaker, I got lost in the creative process and neglected to follow proper accreditation ... I'm embarrassed that I failed to credit @danielclowes for his original graphic novella Justin M. Damiano, which served as my inspiration ... I was truly moved by his piece of work & I knew that it would make a poignant & relevant short. I apologize to all who assumed I wrote it. I deeply regret the manner in which these events have unfolded and want @danielclowes to know that I have a great respect for his work."

Well played, sir. Now get back to making robot-car-aliens movies. They seem to be less of a hassle.
