Boy am I glad to see this topic, Mr.M!
I am hyped to see this movie. I've been following its progress since the early days on the official board and a couple of (better) fan boards. If anyone go'es to those my name is Dinobot-Sledge.
I knew that there would be changes made (what possesed them to give Prime hotrod flames?) but now that the voice actors are being revealed, things are looking up. Peter Cullen, the original Optimus Prime, is recurring his role, Hugo Weaving (LOTR Elrond) has been cast as Megatron, Kieth David (Spawn, Goliath) has been cast as Barracade and Frank Welker, the original Megatron, is apparently going to voice one of the decepticons. (my money's on Frenzy)
I think this film will turn out okay. I dislike Bay but hopefully, Speilburg will keep him in line.
