Today we're celebrating the 31st birthday of Ryan Gosling. He got his start in television in the mid- to late-1990s, appearing most extensively in shows like "Breaker High" and "Young Hercules." He nabbed his first role in feature film in 1997's Frankenstein and Me and provided his first truly memorable appearance in 2000's Remember the Titans. From there, he held roles in some smaller independent films, but he burst onto the national scene as the male lead in 2004's The Notebook opposite Rachel McAdams. Since then, he's gained critical acclaim for his performances in 2006's Half Nelson, 2007's Lars and the Real Girl and 2010's Blue Valentine. He's most recently been seen in 2011's Drive and Crazy, Stupid, Love., and you can currently see him in The Ides of March. So, to celebrate his birthday, I've created a list of my five favorite Gosling roles. Help me celebrate and wish Mr. Gosling a happy 31st birthday!
