Hey, It's That Voice!: The German dub is an interesting case. For a change, Bill Murray isn't voiced by Arne Elsholtz who is also Tom Hanks' German voice but by Manfred Lehmann who is usually Bruce Willis' German voice and hams it up even beyond his Gérard Depardieu standard. Robert Mitchum sounds as usual, namely like John Wayne (Arnold Marquis), and Gerd Duwner (Ernie) supplies Buddy Hackett's voice. Also, Edgar Ott as the TV Ghost of Christmas Present. If that ain't cool...
