Make Crust:
Preheat oven to 350F.
 In a bowl stir together crumbs, butter, and sugar and press on bottom
 and side of a 10-inch (1 1/2-quart) pie plate. Bake crust in middle
 of oven until crisp, 15 to 20 minutes, and cool on a rack.
Make filling:
 In a metal bowl set over barely simmering water melt chocolates,
 stirring, until smooth and remove bowl from heat. In a heavy saucepan
 (about 3 quarts) whisk together sugar, cornstarch, salt, and egg
 yolks until combined well and add milk in a stream, whisking. Bring
 milk mixture to a boil over moderate heat, whisking, and simmer,
 whisking, until thick, about 1 minute. Force custard through a fine
 sieve into a bowl and whisk in melted chocolate, butter, and vanilla
 until smooth. Cover surface of filling with plastic wrap and cool
 completely.
 Pour filling into crust and chill pie, covered, at least 6 hours or
 overnight.
 In a bowl with an electric mixer beat cream to soft peaks. Beat in
 sugar and beat cream just to stiff peaks. Spoon whipped cream
 decoratively onto pie and sprinkle with grated chocolate.
