Shia LaBeouf wore a brown paper bag over his head to the German premiere of his new movie.

The 27-year-old actor, who announced he was retiring from ''all public life'' last month, refused to show his face at a red carpet screening of 'Nymphomaniac' in Berlin on Sunday night (09.02.14).

He cut two eye-holes into the bag and wrote the words ''I'm Not Famous Anymore'' in black capital letters on it before placing it over his head and attending the event in a dapper tuxedo, according to gossip website TMZ.com.

The 'Transformers' star was clearly eager to make a statement just an hour after storming out of a press conference for the movie.

When asked if it was uncomfortable filming sex scenes for the film, Shia let his co-star Stacy Martin answer first.

After hesitating for a moment, the dishevelled-looking star, who was missing a bottom tooth, then quoted retired French soccer player Eric Cantona's famous words to answer unwanted media attention: ''When the seagulls follow the trawler, it's because they think sardines will be thrown into the sea. Thank you very much.''

He then walked off stage much to the amusement of Stacy.

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.''
