Fans no doubt will recall that when we last saw Megatron, Sam had rammed the All Spark cube into his chest, thereby destroying him.

Despite this apparent death, rumours have been circulating the villain was going to make a comeback. Director Michael Bay went so far as to flatly deny the rumour, telling Empire: ``He’s not in this movie.’’

Turns out Bay was fibbing.

``I’ve already done it,’’ Weaving (Megatrons voiceactor) 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.
