This is so sad.
Actor Steve Landesberg, most famous for his role as Det. Sgt. Arthur Dietrich on the show Barney Miller, but most recently as the HIGHlarious pediatrician Jason Segel sees over a potential STD in Forgetting Sarah Marshall, passed away early this morning after a long battle with cancer.
Our thoughts are with his family and loved ones during this difficult time.
He will be greatly missed.
