I'm sure JJP can use anything from the film they want. We've already seen video clips of Dorothy and Oz talking Toto escapes and Emerald City Multiball). I think they might have just been using the custom voice calls because people wanted to hear them and possibly to guage whether we liked them. They sound pretty rubbish to me especially Glenda. I'd rather hear only clips from the film and then maybe one or two of the best soundalikes or even just 'narrator' types do all the pinball specific call outs. Attempting to do half arsed impressions of some of the most famous film characters EVER is just going to come across as a cheap knock off despite JJP's intention to make this a 1st class presentation.

Tron's sound is so good. I didn't even know some of the music was custom.
