Dennis Quaid puts the moves on the always-sexy Rene Russo in their new romantic comedy, "Yours, Mine and Ours," which demonstrates what can happen when two combined families suddenly live under the same roof.

"It's basically the red states and the blue states coming together," Quaid explained.

Quaid and Russo have a total of 18 kids in the film, but in real life, Quaid only has one child: 13-year-old Jack, whose mother is Quaid's former wife, Meg Ryan.

Last year when "Extra" sat down with the actor, he said he definitely was up to the idea of more kids. Is that still in the plans?

"Yeah sure," he said. "I'm going to go home and work on it again tonight."

"Yeah, she's not really a public person," Quaid admitted when asked how his gorgeous new wife Kimberly is adjusting to life in the spotlight after only a year and a half of marriage. "She even shies away from people who just want to take a snapshot in the living room."

Kimberly's camera-fright certainly hasn't rubbed off on her 51-year-old husband, who shows off his abs in his new movie.

"Yeah, it's all the drugs and surgery," Quaid joked. "I've got a video coming out."

Quaid's "Yours, Mine and Ours" hits the big screen on November 23rd.
