Backward with Help (10/21)

I'm thinking of a famous 20th century writer whose first and last names are 5 and 6 letters long respectively. Perform the following four functions on the name:

1) switch the fourth and fifth letters,
2) take the last letter and place it first,
3) the second to last letter and place it second,
4) the third to last letter and place it third.

Now if you read the letters from right to left, you've got the writer's name again.

Who is this writer?

Hint: A movie bearing the name of one of this author's novels came out within the last ten years.
