Slice one banana and place the slices in the bottom of the graham cracker crust.
In a medium bowl, whisk together the vanilla pudding, banana pudding, heavy cream, milk, and sour cream until smooth and thickened.
Pour the pudding mixture over the banana slices and spread evenly.
Top with Cool Whip, spreading it evenly across the pie.
Cover and refrigerate until ready to serve (at least 2 hours).
Just before serving, slice the second banana and use it to garnish the pie or individual slices.
