It's similar to the bag LaBeouf wore at the Berlin Film Festival premiere of director Lars von Trier's Nymphomaniac.
LaBeouf sits at the table, with his hands palms down on top of it, and does not say anything, no matter what is brought into the room with him. When I asked him if he was talking at all, he barely chuckled, and appeared to smile underneath the bag. At no point did he break eye contact with me, and the paper just underneath the eyeholes of the bag was wet, as if LaBeouf had been crying. He also did not interact with what I brought in, Clowes' book, even after I asked him to read it.
Multiple BuzzFeed staffers visited the exhibit — which is located across the street from BuzzFeed's L.A. office — and all reported similar, and similarly weird, experiences. One staffer, however, did shake LaBeouf's hand before leaving. UPDATE: Fearless BuzzFeed staffer Mike Spohr actually took off the bag from LaBeouf's head, after asking multiple times for permission, and finally receiving a head nod from LaBeouf. At no point did LaBeouf move or speak, and he did not aid Spohr in placing the bag back on his head.
The entire stunt is very similar to artist Marina Abramovic's famous installation "The Artist is Present" at New York's Museum of Modern Art, in which the artist sat at a table across from series of single museum visitors over the course of three months in 2010.
The exhibit is running from Tuesday, Feb. 11, through Sunday, Feb. 16. Apparently, LaBeouf is not sorry on a Monday.
