Halle Berry shimmered in silver at the Los Angeles premiere of her new film 'Cloud Atlas'.

USA Today reports that Halle said she couldn't say no to a part in the epic, centuries-spanning film, based on British author David Mitchell's novel.

The 'Monster's Ball' star plays several roles in the film, including a man.

She told reporters at the premiere: "You have to say yes to something like this."

Halle - who was joined by fiance Olivier Martinez - said she hoped people "walk away having a dialogue about it".

She added: "And really realising the ramifications of all of our actions and all of the choices that we make, and that they do reverberate for generations and generations. Acts of kindness and also acts of cruelty. It really matters."
