Goran Visnjic - Dr. Luka Kovač

As if anyone could fill the Hot Doc vacancy left by Clooney's pediatric hero Doug Ross, Croatian actor Visnjic certainly carved out his own soulful version. The soft-spoken pediatric physician had most of the female staff at County at "hello," ... morebut it was his up-and-down relationship with nurse-then-doctor Abby Lockhart that cemented his character and created the most sparks. After playing the committed doctor with a tragic past, Visnjic moved on after Season 14, and has continued making movies. His upcoming work includes the film "Helen" opposite Ashley Judd, and "Miss Irena's Children," a historical film slated for a May release on CBS for the Hallmark Hall of Fame series.
