“Zack is an incredible actor, an incredible man, a powerful human being, who’s been there for me when I needed him and we shared something really special,” LaBeouf told the crowd. “I love you, dude.”

When Johnson met Gottsagen just before they started filming Falcon, “I was totally bewildered by his purity of heart,” she said. “He is the most loving and embracing person I’ve ever met in my life.”

LaBeouf and Gottsagen then displayed their breakdancing skills together on stage.

“We believe the movie will change the worldview of the people with Down Syndrome,” Gottsagen added.
