Hugo Weaving reckons his new film Cloud Atlas will be "too much" for some people.
The actor joins Halle Berry, Tom Hanks, Jim Broadbent, Susan Sarandon, Hugh Grant and Jim Sturgess to play multiple roles in the movie, set in different locations and time periods.
Hugo told Vulture the multiple genres made it hard to describe the film to people. He added: "It also makes it a hard movie to accept and to watch, because it's out of their experience and therefore it's wrong.
"So I suspect that will be the main problem for some people - because it's unusual, it's like, 'Ehhh that didn't work for me because I've never seen it before and I wanted it to be like this. Why couldn't they do that?'
"But what I think is great about it is that it's actually quite revolutionary in its structure. It's quite playful yet it's a very serious film. It manages to incorporate all these elements amazingly well, but I think for some people it will be too much."
The movie - an adaptation of David Mitchell's novel - premiered at the Toronto International Film Festival and was co-directed by siblings Andy and Lana Wachowski and Tom Tykwer.
Hugo revealed he was a big fan of Mitchell's work.
He said: "Then I heard they were working on the script, so when Andy rang and said, "There's a script coming for you and these are the roles we want you to play," I knew what those roles were. I knew the story and the book. So it was an easy script to read, and a wonderful adaptation of a complex, wonderful novel. I said yes quite quickly."
