Hugo Weaving has played many fascinating characters during his illustrious career but one has proven to be less than memorable for the star.
The Australian actor admits he did no preparation for his voice-over role as the "evil" Megatron in the Hollywood blockbuster Transformers series.
"That's a weird job for me because it honestly was a two-hour voice job, initially. I was doing a play and I actually didn't have time, anyway.
"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 told Collider.com.
"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," Weaving said.
Proving his apathy toward the role, Weaving reportedly drew a blank when asked about Transformers' director Michael Bay.
"I was never on set. I've seen his face on Skype. I know nothing about him, really. I just went in and did it. I never read the script. I just have my lines, and I don't know what they mean. That sounds absolutely pathetic. I've never done anything like that, in my life. It's hard to say any more about it than that, really," he told the industry website.
Weaving made the admission during the interview conducted to support his new film Cloud Atlas, in which he plays six characters. Starring Tom Hanks, Cloud Atlas is being released in Australia in February.
The Aussie actor also stars in the three forthcoming Hobbit films, reprising his role from the Lord of the Rings trilogy. The first film The Hobbit: An Unexpected Journey comes out in Australia on Boxing Day.
