In the movie “Knocked Up,” the character played by Seth Rogen has a get-rich scheme to start a Web site that features Hollywood nude scenes, but his plans are dashed when he learns that another site, MrSkin.com, beat him to the punch.

What’s bad news for the movie’s protagonist turns out to be good news for Mr. Skin, an actual site, which saw a 35 percent bump in new visitors in June, when the movie was released.

But “Knocked Up,” which had permission to feature the site, was not the first to notice it. Mr. Skin had revenue of $5.3 million last year, primarily though $29.95-a-month subscriptions. With more than 175,000 revealing pictures and video clips of about 15,000 actresses (yes, only actresses), the site drew 2.9 million unique visitors in June, according to comScore, the Web traffic tracker.

“We don’t care about cinematography or great acting or anything like that,” Jim McBride, who favors the title chief sexecutive officer, said on the phone from his company’s Chicago offices. “We’re concerned about the nudity — who’s naked, and what they show.”
