Preheat oven to 425°F.

Prepare the 9-inch pie shell.

Spread half of the cherry pie filling in the bottom of the shell.

Set the remaining cherry pie filling aside.

Bake the shell for 15 minutes, or until the crust is golden.

Remove from oven.

Reduce oven temperature to 350°F.

In a separate bowl, combine the softened cream cheese, sugar, eggs, and vanilla.

Mix until smooth and creamy.

Fold in the sour cream.

Pour the cream cheese mixture over the cherry pie filling in the baked pie shell.

Spread the remaining cherry pie filling over the cream cheese layer.

Bake at 350°F for approximately 20-25 minutes, or until the filling is set.

Let cool before serving.
