Shia LaBeouf opted to apologize for plagiarizing author Daniel Clowes' work by writing a message to Clowes in the sky over Los Angeles on Wednesday, Jan. 1.
"I am sorry Daniel Clowes," the message said.
LaBeouf tweeted a black and white photo of the message in the sky on Wednesday and wrote, "CLOUD: - vapor floating in the atmosphere - remote servers used to SHARE DATA - to make LESS CLEAR or TRANSPARENT."
Last month, LaBeouf released his short film "HowardCantour.com" online and shortly after its release, outlets like Buzzfeed noted similarities between LaBeouf's film and Clowes' 2007 comic "Justin M. Damiano."
Both center on a film critic, which is played by comedian Jim Gaffigan in LaBeouf's film. Clowes himself commented on the controversy to Buzzfeed.
"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," Clowes told the website. "I actually can't imagine what was going through his mind."
Shortly after the reports compared the two works, LaBeouf admitted that he didn't properly credit Clowes' influence on the short.
"In my excitement and naivete as an amateur filmmaker, I got lost in the creative process and neglected to follow proper accreditation," he explained in a tweet on Dec. 16.
He later added, "Im embarrassed that I failed to credit @danielclowes for his original graphic novella Justin M. Damiano, which served as my inspiration."
Since then, LaBeouf has tweeted multiple apologies, most of which have lifted quotes from other apologies by the likes of Tiger Woods, Facebook founder Mark Zuckerberg, Alec Baldwin and Russell Crowe.
Prior to the skywriting tweet, LaBeouf wrote on his Twitter account, "2014 Resolution - I need to work on being a less controversial tweeter."
