The Juilliard-trained actress didn't even blink. Knowing Chaplin would follow her, Chastain simply walked offstage for a beat while continuing the scene.

Chaplin reappeared at the end of the show when Chastain held him in her arms during her final bow, according to the New York Post, which first reported the story.

"What can I say?" Chastain tells E! News. "He's going to break into the business one way or another!"

Chastain has two other dogs, Radley and Roman. No word if they're trying to break into the biz, too.
