The not-so-incredible Hulk! Mark Ruffalo revealed at the Hollywood premiere of Avengers: Age of Ultron on Monday, April 13, that his three kids don't think their dad is cool, even if he happens to play Marvel's big green superhero, The Hulk.

Ruffalo, 47, brought his wife Sunrise Coigney and their three kids Keen, Bella, and Odette, onto the red carpet outside L.A.'s Dolby Theatre on Monday. "Oh, they love this," he told Us Weekly and other reporters. "This is cool for them."

What's uncool, not surprisingly, are their parents. "They're like, 'You're not that cool,'" Ruffalo joked. "'Why do you keep saying no to me?' 'Why don't I get my computer all the time?'"

The Foxcatcher actor said his kids — who have seen "Hulk dad" when he gets mad — even refuse to heed his warnings. "They're like, 'Big woop, dad. I want to see you angry.' That's what they say to me. 'I'm going to get you angry.'"

Ruffalo, for one, has been enjoying his stint as a superhero. "I'm still having fun," the Oscar nominee told Us. "But I'm only two [films] in. Some of these guys, they're like in six or seven movies, and you should ask them if they're still having fun."
