petrieboy There's more to a performance than just the performance, Mannerisms, chemistry and spontaneity has much to do with it as well. Dubbing performances may make the voice sound closer, but it takes much of the spark out of a performance. See Fozzie and Piggy's scenes from Muppets Tonight. Just something missing. Puppeteering is not an easy job at all. It takes years of training. You can't just hand a voice actor a puppet and hope he catches on in a month or two. I still don't understand what you think is wrong with Piggy's voice. I think it's incredible. Entertainment Weekly was even fooled into thinking it was Frank. Fozzie and Piggy were the only characters they pointed out, giving Frank kudos for his return! LOL!
