 When Bumblebee introduces himself to Sam and Mikaela, speaking  through the radio, he plays the sound bite, "Across the immense gulf  of space"; the voice is that of Orson Welles (qv) from his  infamous 1939 radio broadcast "The War of the Worlds." Wells  provided the voice of the planet devouring transformer named Unicron  in _Transformers: The Movie, The (1986)_ (qv) which was Welles  final film performance.
