Thaw the pie crust based on the recommendations on the box. OR make your homemade pie crust, place in the pie dish and set aside.
Preheat the oven to 350F.
Evenly lay the chopped pecans along the bottom of the pie crust and set aside.
In a medium bowl mix the corn syrup, eggs, melted butter, brown sugar, vanilla, cinnamon and mix well.
Pour the pie filling slowly on top of the pecans. The pecans will rise to the top; if you see any empty spots, you can sprinkle a small amount of chopped pecans to ensure an even spread.
Top with halved pecans.
Bake for 50-60 minutes or until the center is just a little bit jiggly.
Remove the pie from the oven and allow to cool completely on a wire rack.
Slice and enjoy with whipped cream or ice cream.
