The role of Zapp Brannigan was written for the late Phil Hartman, who died before the show started and West was given the role. West has described his interpretation of Zapp Brannigan's voice as an imitation of Hartman, but described the actual vocalizations of the character as being based on "a couple of big dumb announcers I knew." "Futurama" was renewed by Comedy Central as four direct-to-DVD films broken into 16 television episodes. West reprised his roles for these films and was signed on for two new 26-episode production seasons (four 13-episode air seasons) of "Futurama" which aired summers of 2010 to 2013.
