Shia LaBeouf stages L.A. art installation titled “#IAMSORRY�

We know this to be true: Shia LaBeouf is sorry. Sincerely sorry.

What for? In December, LaBeouf used work, without giving credit, by the illustrator Daniel Clowes in his short film, “HowardCantour.com.�

After a storm of plagiarism allegations, LaBeouf issued an apology that read, in part: “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.�

Now LaBeouf is putting on a collaborative art installation titled “#IAMSORRY� with Finnish performance artist Nastja Säde Rönkkö and painter Luke Turner at L.A.’s Cohen Gallery. It will run from 11 a.m. to 6 p.m. Tuesday through Sunday at the gallery, which is at 7354 Beverly Blvd.

Will the exhibit be as strange as LaBeouf’s behavior lately? On Sunday, the actor showed up at the Berlin premiere of Lars von Trier’s “Nymphomaniac: Volume I,� which features LeBeouf, wearing a black tuxedo with a paper bag over his head that read: “I Am Not Famous Anymore.�

That, of course, is not an accurate statement. Fame is just turning into infamy.
