You probably know handsome Eric Dane best for his role as Dr. Mark Sloan, aka Dr. McSteamy, on Grey’s Anatomy, but he has appeared in a number of TV and theatrical movies. These include X-Men 3: The Last Stand, Feast, and Helter Skelter (TV). His acting career started way back in 1991, in an episode of Saved by the Bell, and followed by various appearances in The Wonder Years, Married… with Children, Roseanne, Charmed, and more.

Aside from Grey’s Anatomy, Dane has no current projects listed. He is currently battling skin cancer – the most common form of cancer in the United States. Eric, we wish you well. [UPDATE: The OK! mag article is apparently over-emphasizing his "battle" with cancer.]

The video clip below shows you why his Dr. Mark Sloan character is called McSteamy.

Twenty-six year old Ben Barnes only started his professional acting career in 2006, in an episode of the TV series Doctors, but he’s already getting credited for several movies. (Though he did appear as a performer, under the moniker Hyrise, on Making Up Your Mind and Liquid News, both in 2004.)

His first movie was Stardust, but he’s getting recognized for his appearance as Prince Caspian in The Chronicles of Narnia: Prince Caspian. It’s the second movie in the series, based on the third book in the classic fantasy novel series by C.S. Lewis. It opens May 16th. Barnes will also be in the followup, The Voyage of the Dawn Treader in 2010, as well as Bigga Than Ben (2008) and Easy Virtue (2009).
