Actor Hugo Weaving says providing the voice for evil robot Megatron in the hit Transformers film trilogy was "meaningless" to him.
Speaking to Collider.com, Weaving owned up to knowing nothing about the three films, which raked in millions at the box office in 2007, 2009 and 2011.
Weaving, who stars as elf Elrond in Peter Jackson's upcoming Hobbit trilogy, even admitted he had spent only two hours providing Megatron's voice in each film.
"It was one of the only things I've ever done where I had no knowledge of it, I didn't care about it, I didn't think about it," Weaving said.
"They wanted me to do it. In one way, I regret that bit. I don't regret doing it, but I very rarely do something if it's meaningless. It was meaningless to me, honestly. I don't mean that in any nasty way. I did it.
