6. Algrim the Strong/Kurse

Amongst those listed as part of the
Dark World cast, London-born Adewale Akinnuoye-Agbaje, who has appeared in
The Bourne Identity and 2011s
The Thing (and will appear in Sylvester Stallones upcoming
Bullet to the Head), has been announced to play Algrim, a Dark Elf who, in battle with Thor, is dropped into a molten pit, re-emerging as the demonic

Former

The Dark World as Malekith, the leader of the Dark Elves of Svartalfheim, who covets the Casket of Ancient Winters (which we see in the first
Thor). This could provide the main plot of the film that features a huge role from Tom Hiddlestones Loki. In the comics, Malekith in unleashed by the King of the Fire Giants,
Surtur, which could suggest we may see more from the nine realms...
