Why was Conan so nervous early in the shows run?
You try replacing Letterman and see how cool you are. Seriously, the show was rushed into production to fill the void left by Letterman, and on top of this pressure, Conan didn’t have any talk show experience before this job. He was a writer they put in front of the camera. Under this tremendous pressure, Conan was certainly at least a little edgy during his early run. As the show progressed and settled into its own rhythm, coming out of Letterman’s long shadow, and as Conan gained on the job training in performing on a talk show, the show has shown a steady improvement that continues to this day.
