Dame Helen Mirren was reportedly paid £500,000 by Nintendo to star in a Wii Fit Plus advert.
The 65-year-old actress received the bounty for two days work shooting ads designed to attract over-50s to the game, according to MSN.
"Nintendo insisted they wanted Helen and no one else," a friend of Mirren said. "They wanted an older, more attractive woman to show that the Wii isn't just for children."
The actress says in the ad: "You need never get bored as every day you can tailor a new workout."
The original Wii Fit topped the UK chart for about a billion weeks. Check out CVG Mike playing below.
