Though he is well known for his role as Brad’s also handsome yet reserved big bro, to me, he will always be Hardy Jenns (with two N’s) from Some Kind of Wonderful. Thankfully, he grew into softer roles like Lucas’s beloved Uncle Keith on One Tree Hill and left the A-hole role to his on-screen brother Dan, who shot and killed him. (Talk about sibling rivalry.) He guest-stars regularly on series like CSI: Crime Scene Investigation, The Mentalist, and Criminal Minds. Set your DVRs!
