Heat oven to 375° F. In large bowl, beat margarine and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Add chocolate, instant coffee and rum; mix well. Stir in flour and 1 cup chopped walnuts; pour into pie crust.
Bake 25 minutes. Cool.
Chill 1 to 2 hours before serving. Top with Shoney's Hot Fudge, or whipped cream, or ice cream if you prefer. (Note: I would probably prefer them all!)
