Chris Pratt’s son Jack loved seeing his dad in “The Super Mario Bros. Movie”.

Pratt shares 10-year-old Jack with his ex-wife Anna Faris, telling ET Canada’s Carlos Bustamante of how the youngster reacted: “I did a sneak screening early, and so I took Jack and a bunch of his friends and they loved it.

“His immediate reaction was, he went home immediately, started playing Smash Brothers on his [Nintendo] Switch. They loved it, man. The kids went crazy for it.”

The star shares daughters Lyla and Eloise with wife Katherine Schwarzenegger, as well.
