Shia LaBeouf, an actor whose erratic behavior often veers into the realm of bizarre performance art, has invited us all to watch him watch his movies — all 29 of them, in reverse chronological order.

After spending about 24 hours camped out in the Angelika Film Center on Houston Street in Manhattan, Mr. LaBeouf was still going strong on Wednesday morning with his “All My Movies” project. At the theater and online, people could watch a live stream that showed Mr. LaBeouf staring at the movie screen, wearing a white hooded sweatshirt and a blank expression.

Mr. LaBeouf’s public personality is complex. He began acting as a child and grew up to prove his bankability through steady work on big-budget films. But offstage, he has been unpredictable, and his frequent run-ins with law enforcement, dating back almost a decade, tend to involve alcohol.

As the lines of people at the theater suggested, he inspires some public fascination. Many wonder about the proper way to pronounce his name (shy-UH luh-BUFF). Some created memes that he is a cannibal.
