I always loved the TV series over the movies, relationship between Alan, Peter & Galen was special and you could see that they all went to bat for each other despite how hopeless their situations were at times. 91 is a DAMN GOOD RUN! He lived the life!! As you can see in his resume. I will always treasure the series when I pull it out of the library and pop a dvd into the dvd player.
RIP to Mr. Harper and condolences to his family and fans.
