Dane, who plays Nate's problematic father Cal Jacobs, is undoubtably best known for playing the womanising ladies' man of Grey-Sloan Memorial Hospital, Mark Sloan aka McSteamy on Grey's Anatomy. Post-Grey's, Dane starred as the lead, Tom Chandler, in action-drama The Last Ship. And, we can't forget that he was in the 2008 tearjerker Marley and Me.
