Kate Hudson: Owen Wilson Hilarious

What would you do with the world's worst houseguest?

In the new comedy "You, Me and Dupree," Kate Hudson plays a newlywed facing that problem. As she and her husband, played by Matt Dillon, return from their honeymoon, they get a surprise visit from their free-spirited best man, portrayed by Owen Wilson, who moves in after losing his job and his home.

On The Early Show Monday, Hudson described the film as "really funny. Really fun. And really sweet, actually. There's something really sweet about the movie."

And funny was the theme off-camera as well as on, apparently.

"It was unbelievable," Hudson told co-anchor Harry Smith. "I don't think I've ever laughed harder with anybody (than Wilson) I really — you know, I really like to laugh and, God, he just got me. There were some scenes I couldn't even get through. It made a lot of people frustrated!"

What's more, Hudson added, "Matt was really funny, too," despite not having many funny lines in the movie. "But his sort of straight and determined focus, in context, is quite funny."

Hudson hinted that she had a crush on Dillon years ago, saying, "I think it was that sort of Matt — we were saying, like, in the '80s, was like, I was a little girl in the '80s," and Dillon was "kind of a fixture in little girls', you know, minds."

She credited mother Goldie Hawn and Kurt Russell, Hawn's longtime significant other, who Hudson considers her father, with giving her the grounding she needed as she grew up to enable her to grow into an adult in control of her life.

"You know," Hudson said, "I guess I just do the best — I don't know. … I feel like everybody makes mistakes and everybody's lives go through ups and downs. And I just feel really — I feel like I have a really — my parents, my mom and Kurt really did — when you feel like you have a solid back, something to fall back on, I think it makes everything a little bit easier, and I think it makes you — allows you to be a little more carefree, maybe.

"I feel like my parents really just provided a great upbringing for all of us that was about us all the time. You know, we never felt like anything got in the way of what our family was and how we chose to spend that time together."

Hudson, a mother herself now to 3-year-old Ryder, is married to musician and Black Crowes front man Chris Robinson.

She admits her son is a handful, saying, "He's almost 3, so I'm constantly running around the house. And he's heavy. So you're carrying a 3-year-old and running around," and that helps her stay in shape!
