Anybody else watch Modern Marvels? I could SWEAR that both Doom Doors sounds are played in quick succession at the end of the theme song. (Specifically, the last 4 notes) Listen to it again, see if I'm right or rightly insane.

One could also call this trope "Daggerfall Doors", since the characteristic door screech&metal-thump sample from Daggerfall is frequently used in fantasy/historical movies. Also I believe the cast-spell sound from Dag is present quite frequently in fantasy.

Unfortunately I don't have specific examples at hand.
