Films from Pixar and Dreamworks along with computer games with increasingly sophisticated graphics have prompted Disney to re-evaluate the 71 year-old character.
Disney earns around £3 billion from the Mickey Mouse brand every year. Mickey has kept his look almost unaltered over the years but will now take on a ‘cunning and cantankerous streak' for a new Disney video game, Epic Mickey, to be released next year.
Disney will assess everything from the way he walks and talks to his appearance and what his house looks like at Disney World.
Epic Mickey will be released for the Nintendo Wii console and set in a cartoon wasteland inhabited by forgotten and retired Disney creations. Players can opt to be a co-operative, helpful Mickey or a more destructive version that starts to resemble a rat.
