Zork Nemesis Easter Egg - Four Skulls Movie

Location: Castle Irondune dungeon.
1) Once in the Irondune dungeon (torture chamber, not the cell block), look along the right-hand wall. Zoom into the second table from the entry door.
2) On this table is the skull-crushing torture implement, a skull, and what appears to be a twisted piece of metal.
3) Although the cursor does not highlight, click on the piece of metal.
4) You'll see a movie about 'Four Skulls'.
5) This egg is a 'one-off' -- it can't be repeated without restoring a game.
