Check out Baldwin’s speech at the dedication of his star on the walk of fame. It was very similar in content, less punchy, but very similar to the speech he gave in 30 Rock’s 100th episode. He’s very aware of his career’s ups and downs and the fact that 30 Rock breathed life into what was a dead career.
I need to watch it again and see if they worked in a Beetlejuice reference because with both him and Michael Keaton in the same scene that would just have been right up 30 Rock’s alley. If they did it was a subtle one that I missed on the first viewing.
