"Transformers" star Shia LaBeouf could be facing legal trouble.
The actor recently admitted to borrowing a graphic novelists' work for his short film, "HowardCantour.com" and failing to give the author credit.
Now – the novelist is pursuing his legal options but hasn't said if he'll sue, CNN's Nischelle Turner reports.
LaBeouf has been apologizing profusely on Twitter all week but it turns out his apologies may be plagiarized too.
The film was made available online Monday, and things quickly spiraled out of control when bloggers noticed that LaBeouf's short film bared a striking resemblance to author Daniel Clowes' comic "Justin M. Damiano."
The 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.
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.
Early Tuesday morning, LaBeouf decided to tweet his thoughts on the kerfuffle, culminating in the mea culpa, "I f****d up."
"Copying isn't particularly creative work. Being inspired by someone else's idea to produce something new and different IS creative work," he tweeted.
"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."
