>>10994396>do is a voice IN THE STYLE of that actor. An iconic example of this is Zapp Brannigan from Futurama where it was cast for Phil Hartman originally in March of 98 but after his tragic death a few months later the roll was placed on Billy West who stated he made the character a tribute to Phil in how he performed the character listening to recordings of the late Hartman to ready himself when playing Zapp.
