Yesterday, actor-director Shia LaBeouf's short film was posted online in its entirety, after making its debut at the 2012 Cannes Film Festival. Despite the fact that the short film was nearly 18 months old, and it had debuted at other film festivals such as the St. Louis Film Festival and the Phoenix Film Festival, it was only revealed last night that the work was plagiarized from Daniel Clowes' 2007 comic Justin M. Damiano.

The short, which stars Jim Gaffigan as online film critic Howard Cantour, follows a day on the press junket circuit, with Thomas Lennon and Portia Doubleday co-starring as Howard's colleagues, and Dito Montiel portraying the filmmaker Howard once idolized. A vast majority of the dialogue is lifted word-for-world from Daniel Clowes' comic, although the character names have been changed.

The credits make no mention of a screenwriter, or that the work was based on or inspired by Daniel Clowes' comic. Buzzfeed caught up with the author, who revealed that he was not aware his work was being plagiarized.

"The first I ever heard of the film was this morning when someone sent me a link. I've never spoken to or met Mr. LaBeouf. I've never even seen one of his films that I can recall - and I was shocked, to say the least, when I saw that he took the script and even many of the visuals from a very personal story I did six or seven years ago and passed it off as his own work. I actually can't imagine what was going through his mind."

Shia LaBeouf has mentioned before that he is a fan of Daniel Clowes work, but he the author's work didn't come up in an interview with ShortOfTheWeek, the website which posted yesterday.

"I know something about the gulf between critical acclaim and blockbuster business. I have been crushed by critics (especially during my Transformers run), and in trying to come to terms with my feelings about critics, I needed to understand them. As I tried to empathize with the sort of man who might earn a living taking potshots at me and the people I've worked with, a small script developed."

Last night, the actor fessed up to his plagiarism with a series of tweets.

However, it appears that even his apology was pilfered from a post on Yahoo! Answers. The actor has been accused of plagiarism before, after it was revealed he copied quotes from an Esquire magazine article into an email he sent to Alec Baldwin, which later leaked online.
