Shia LaBeouf is so meta, he makes our postmodern brains explode.

His latest performance piece? Watching all of his movies -- 'scuse, #ALLMYMOVIES -- in reverse chronological order at the Angelika Film Center. And you are invited to watch. 

The Shia-a-thon started Tuesday at noon and continues for 72 hours. If you love a bargain, it's free. 

Head down to 18 W. Houston St. and watch in person, or keep tabs on the actor-viewer via newhive.com, which is streaming the experience, the camera looking upward, positioned (we hope) on the actor's lap.

Celebrities -- they really are #justlikeus.
