"IN town to promote his rather excellent new Aussie film, Last Ride, Hugo Weaving let slip he’ll be returning as the voice of Megatron in Transformers: Revenge of the Fallen.
Fans no doubt will recall that when we last saw Megatron, Sam (Shia LaBeouf) had rammed the All Spark cube into his chest, thereby destroying him.
Despite this apparent death, rumors have been circulating the villain was going to make a comeback. Director Michael Bay went so far as to flatly deny the rumor, telling Empire: ``He’s not in this movie.’’
Turns out Bay was fibbing.
``I’ve already done it,’’ Weaving says, adding Bay had told him to keep the news hush-hush. ``He’s over in LA and we were working on the video split sort of thing and I had this strange conversation where he seemed to imply it was all a big secret. So there you go I’ve given you the secret scoop.’’
So how is Megatron resurrected?
Weaving is coy about revealing too much, but does give a tiny hint.
``I think in the last one, doesn't Optimus Prime pick up a little bit of, a little shard of the cube, or the thing that’s left, and he takes it with him. Maybe there’s something there… but I don’t know,’’ he laughs. "
If the Megatron rumor is true, which I think it is due to the above article as well as the Megatron Toy announcement last month, then that's cool. Megatron is THE main villain in the Transformers Universe, sure there are other villains that poke there noses out every now and then but Megatron is the villain that always seems to be around. Even sometimes being stuck in the back ground Megatron is still present. It would take an enormous amount of screen time in one movie showcasing Megatron for him not to be in a future sequel. This off course is not the case with the first installment in the Transformers movie franchise.
