As Nimoy was there from the very beginning, I was hoping he would be around for the 50th anniversary. It will be a tad bittersweet now.
I watched The Menagerie a few weeks back, and I still marvel at how they integrated The Cage into the show's continuity. As I kid, I really thought they made up new costumes and changed the sets to show what happened during Pike's command. And Spock really does look a lot younger in The Cage.
