usually I'm not comfortable with hearing the voice actor in a live action movie. sometimes when I hear an actor is going to play a cartoon character or a voice I look up if he or she has ever played in a cartoon once. David Warner in any case, ever since I hear he is considered as Shockwave I've researched what cartoons he played in. so far the only one I can find was Batman Ra's al ghul. But just today I found other cartoons he voiced. Example: Toonsylvania as the doctor YouTube - Toonsylvania Melissa Screetch Here there be Monsters * Darla Doily Or Buzz lightyear as Lord Angstrom YouTube - BLoSC Mira's Wedding part 1/3 Maybe Grim Adventure's Nergal And lets not forget Batman Ra's Al Ghul YouTube - Batman and Ra's al Ghul So, with these voices do you think David Warner will make a great Shockwave?
