You can excuse any actor on the set of a Transformers film of phoning it in for a paycheck but in the case of Hugo Weaving, that’s exactly what he did. In fact, the voice of Megatron has never met director Michael Bay.
"Michael Bay talks to me on the phone. I’ve never met him. We were doing the voice for the second one and I still hadn’t seen the first one. I still didn’t really know who the characters were and I didn’t know what anything was."
Well, I saw the movies and I still don’t really know who the characters are or what anything is. My hope for the sequel is that everyone (robots included) wear name tags. And speaking of the sequel, from Weaving:
"Oh no. They’re not making another Transformers, are they?"
My sentiments exactly. (from The Age)
