Nicole Kidman has become the face of a campaign for a new Nintendo game.
The actress has signed up to promote the company's latest venture More Brain Training from Dr Kawashima.
It claims to help the user's brain stay active through a series of "exercises".
Nintendo said she was picked to appear in the adverts because of her "universal appeal".
Kidman, who turned 40 this month, said: "I love the concept that Nintendo is reaching out to new audiences with their self improvement products like Brain Training.
"Most importantly, I've quickly found that training my brain is a great way to keep my mind feeling young."
