Just announced on CBS News. There are some people you are just used to having in the world. Thank you for Spock, and William Bell, and all the other roles that were overshadowed.
As shocking as it is to hear I can't say that I'm all that surprised, that man just did not age that well and seeing him on Fringe I really didn't think that we'd have him with us for all that much longer. Still sad to hear though.
