The Shia LaBeouf movie theater meme hails from a scene where the actor is captured smiling warmly while watching a film in a theater. This image comes from a performance art piece called #ALLMYMOVIES, where LaBeouf watched all of his own movies in a marathon over the course of three days, live-streaming his reactions. The meme captures a moment of pure joy and self-appreciation that resonated with the online community, who quickly identified with the expression as embodying proud, supportive, or even humorously self-delusional feelings.
