Patrick Dempsey on Being a Hot Doctor and a Doting Father

"Kids are amazing," Dempsey said. "They change your life for the better and. … It's unlike anything else."

Before he gets back on diaper duty, Dempsey is returning to the big screen, starring opposite Oscar winner Hillary Swank in "Freedom Writers." His role is small but instrumental: Dempsey plays the husband of an intrepid inner-city teacher.

"I didn't need to take a movie just to star in a movie," he said. "I wanted to be a part of something I believed in."

While Dempsey relished his time in the movie, he's not hanging up his scrubs yet. The actor will continue to make his fans swoon as "Dr. McDreamy." As for what McDreamy actually means, Dempsey has a theory.

"[He] sort of represents the perfect male," he said.

Millions of "Grey's Anatomy" viewers would likely agree.
