Largest age difference between actor's actual age and age of the character?

Mary Pickford practically made a career out of playing roles too young for her. At about age 28, she played the title role in Pollyanna who I think was supposed to be 11. At about age 37 she played the title role in Coquette who I think was supposed to be about 18. At 41, she even screen-tested for the role of Alice in a planned Alice in Wonderland movie. Alice was seven years old in the book. That film was never made, which I think is a mercy.

She was mentioned when this thread was fresh.
