Shia LaBeouf is starring in a new silent art installation in Los Angeles.
The 27-year-old actor stormed out of a press conference and wore a brown paper bag, printed with the words "I Am Not Famous Anymore,' over his head to the premiere of 'Nymphomaniac' in Berlin on Sunday night (09.02.14).
This comes after announcing he was retiring from "all public life" last month, launched his free week-long show titled '#IAmSorry' at the Cohen Gallery on Beverly Boulevard on Tuesday (11.02.14).
A collaboration between the 'Transformers' star and artists Nastja Sade Ronkko and Luke Turner, the show invites visitors to choose from various "implements" associated with the actor's career.
This includes a whip similar to the one in 'Indiana Jones and the Kingdom of the Crystal Skull' and a bowl of folded up notes, each bearing Twitter comments about Shia.
Visitors are then are led into a room to see the actor sitting at a table with the now-famous brown bag over his head.
But the showcase has already come under fire for being similar to Lady Gaga's pal Marina Abramovic's famous suffering-in-silence-and-in-public exhibits, documented in the 2012 film 'The Artist Is Present.'
Marina also retweeted a message from documentary distributors Dogwoff on Twitter that read: "Shia LaBeouf taking a leaf from Marina Abramovic with #IAMSORRY performance art?" with a link to her film.
Shia announced in January that he was taking a step back from the limelight after he was forced to apologise for plagiarising author Daniel Clowes' graphic novellas, 'Justin M. Damiano,' for his short film 'HowardCantour.com'.
He wrote on Twitter: "In light of the recent attacks against my artistic integrity, I am retiring from all public life." He added: "My love goes out to those who have supported me. #stopcreating."
