Stephen King -- My Favorite Actor in My Films Is ....

Stephen King has written more than 50 novels and most have become movies with huge actors ... yet he can pick a favorite.

Stephen was in D.C. Thursday to accept the National Medal of Arts, when our photog asked a question that by all rights is impossible to answer, yet Stephen did the impossible, choosing from:

-- Jack Nicholson, "The Shining"

-- Morgan Freeman, "Shawshank Redemption"

-- Kathy Bates, "Misery"

-- Michael Clarke Duncan, "The Green Mile"

-- Sissy Spacek, "Carrie"

-- River Phoenix, "Stand By Me"

There are many more, so who do you think Stephen picked?
