In light of recent events with Charlie Sheen, Movie Line has an illustrated piece that gives an overview of actors who have been fired from their own television shows. See http://www.movieline.com/2011/03/a-brief-history-of-actors-being-fired-from-their-television-shows.php for a trip through television history. Some of the firings were obviously justified – drug abuse and unreasonable demands – and some make you think a bit – actresses who became pregnant fired because the show producers couldn’t figure ways to incorporate it into the show or who thought it was unseemly.
