You know him on screen as Opie on "The Andy Griffith Show," Steve Bolander in George Lucas' "American Graffiti" and, of course, Richie Cunningham on "Happy Days" -- and we could take all day to mention the movies where a grown-up Ron Howard can be found behind the camera, a list that includes the blockbusters "A Beautiful Mind," "The da Vinci Code" and "Rush."

But where you won't find him is in rehab or in the pages of any of the popular tabloid publications; this former child star has been married to his high school sweetheart since 1975 -- notably without scandal -- and after more than five decades in the business continues to have a nice-guy reputation.
