Marple, the elderly spinster amateur detective, has typically been portrayed by older women, including Margaret Rutherford and Angela Lansbury. In the Disney remake, to be scripted by Mark Frost, Garner will play a younger version with a contemporary spin.
Garner was most recently seen on Broadway in Cyrano de Bergerac and will be starring on screen in the upcoming remake of "Arthur."
A date for the film has not yet been set.
