Mark Ruffalo and his son Keen took a stroll together in New York City on Sunday (July 22). The 11-year-old had on a Hulk t-shirt. Fitting since his dad played The Incredible Hulk in The Avengers.
Mark is currently shooting Can A Song Save Your Life? in the city with Keira Knightley, Hailee Steinfeld, and Adam Levine.
He and his wife Sunrise Coigney also have two other children, Bella, 6, and Odette, 4.
He once admitted he can have a temper when parenting.
“I have a hair-trigger temper. And I have lots of practice: A parent who doesn’t yell at (his) kids isn’t spending enough time with them.”
