For the bread pudding: Blend the cream, pumpkin, granulated sugar, brown sugar, pumpkin pie spice, vanilla extract, eggs and vanilla bean until mixed well. Place the French bread in a 1-gallon aluminum pan. Pour the mixture over the French bread and let sit for 30 minutes. Bake for 1 hour or until firm.
For the rum sauce: Blend the cornstarch with 1/2 cup water in a small saucepan. Add the cream, granulated sugar, butter and rum and cook over low heat, stirring occasionally, until thick. Serve the sauce with the bread pudding.
