"This is the first time my youngest son is ever going to see me in a movie, so we'll see what happens," Cage said at the Cinema Society and Amnesty International screening of The Sorcerer's Apprentice, due in theaters July 14, in New York.
Then, turning to his wife of six years, Alice, he asked: "What does Kal think I do for a living?"
Savvier than the star possibly suspected, she replied: "He knows that his daddy makes movies. He's starting to see the trailers."
Though watching his dad fling plasma bolts proved a bit overwhelming for the little guy, who left the screening midway through, Cage decided the family-friendly flick would be the perfect introduction to his body of work.
"My movie comes on TV at home [and] I always shut it off," he said. "I don't like him seeing my movies. But I thought tonight would be a special treat ... I thought that'd be fun for [him] to see why Daddy goes to work."
