( CNN ) -- Shia LaBeouf says he is n't famous anymore , but actually he 's rarely been in a brighter spotlight . For the past several weeks , the 27-year-old actor has gotten more than his fair share of publicity thanks to a rash of bizarre behavior , from his reaction to allegations of plagiarism to his recent stunts at the Berlin Film Festival , where Lars von Trier 's `` Nymphomaniac -- Volume 1 '' premiered Sunday . At a news conference to promote the sexually explicit film , LaBeouf answered just one question before abruptly walking out of the room 10 minutes after the event began . According to reporters present in Berlin , LaBeouf was asked to describe what it 's like to do a movie that includes so many sex scenes . In response , the former child star quoted French soccer player Eric Cantona : `` When the seagulls follow the trawler , it is because they think sardines will be thrown into the sea . '' As the room tried to make sense of his answer , LaBeouf made his exit . And that was just the prelude . Later on at the `` Nymphomaniac '' premiere , LaBeouf showed up on the red carpet wearing a tuxedo and a paper bag over his head . As if that was n't eye-catching enough , the mask , which was outfitted with two holes for his eyes , had `` I AM NOT FAMOUS ANYMORE '' scrawled on it in black marker . To LaBeouf 's fans , that line is all too familiar . He 's tweeted the phrase , in all caps , every day since January 20 . Making this situation even more curious are the series of events that led up to his `` NOT FAMOUS '' proclamation . In December , LaBeouf was hit with allegations that he plagiarized author Daniel Clowes ' work for his short film , `` HowardCantour.com , '' and the actor soon copped to using Clowes ' art without proper credit . `` I f****d up , '' he said at the time in a tweeted statement . `` In my excitement and naivetÃ© 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 . '' A few days after that statement , however , LaBeouf started taking the concept to extremes . He began responding to the vitriol online with more plagiarism , borrowing from mea culpas by Facebook 's Mark Zuckerberg , UK Deputy Prime Minister Nick Clegg and even `` Nymphomaniac '' director von Trier . In January , LaBeouf literally took his apologies to a higher level , hiring an airplane to sky write `` I am sorry Daniel Clowes '' in Los Angeles . Before anyone could figure out what LaBeouf was really up to -- there were rumors that his strangeness was actually performance art -- he announced that he was retiring . `` In light of the recent attacks against my artistic integrity , I am retiring from all public life , '' he said on January 10 . `` My love goes out to those who have supported me . '' Of course , it appears that LaBeouf has a very different definition of what it means to be retired . Not only is the actor still as publicly visible as ever , but he 's also still accepting movie roles . The former `` Transformers '' actor has been cast alongside Bill Murray in `` Rock the Kasbah . ''
