4: Peter Cullen is still the voice of Optimus Prime. 擎天柱仍由Peter Cullen配音。

He damn well better be. The studio probably didn't want to even bother considering a Transformers movie until Cullen signed on. The fan outcry when the first one was in the works was so huge, that there was no chance it would have made any money without him. Prime only has one voice.

他绝对做得更好。Cullen加入之后，制片厂可能根本就不会为一部变形金刚电影烦恼。当第一部出来时，粉丝的尖叫声如此之大，人们毫不怀疑因为他这部电影才能赚到钱。擎天柱只能有一个声音。
