Steve Carell explains to Ellen why he won’t appear in The Office finale.
From Steve’s interview with CNN:
“I figured the character would go back and visit everybody, but he wouldn’t do it on camera at this point,” he said. “I think he had grown past the idea of being in the documentary, that was my take on it. That [Michael Scott] had said goodbye to that aspect of his life, that that’s not what was important to him. I just thought, yeah he’d go back and visit, but he wouldn’t want the camera crew to be documenting it.”
