Owen Wilson has admitted even the most committed guys still check out other women.
The US actor plays Rick, a married dad-of-three who can't resist gawking at the ladies, in Hall Pass and confessed the premise of the movie isn't too distanced from real life.
"Guys really do look. It's a bit like dogs - we look as we're walking. Sometimes it seems like you can't help it," he said.
Owen, the proud dad of two-month-old son Ford with girlfriend Jade Duell, concedes the idea of settling for one woman can seem hard.
"Even if God told you this is the perfect woman and the best match on the planet for you, you'd still want to try number two. And that's a slippery slope because then you'd wonder what the person back in 97th is like," he continued.
In the Farrelly brothers' comedy, Rick gets a "hall pass" by his wife (played by Jenna Fischer), where he gets a week-long break from marriage and has the freedom to do what he wants, no questions asked.
"For a lot of men, it would seem like a dream come true. You remember back when you were single, going out to bars," Owen explained.
"But it's a double-edged sword. If you're going to get a hall pass, that means your wife is too - and chances are they might have more luck than you."
