I'm thinking now we won't see Kurse in any set pics.
Because he'll be all CG.
That would make sense, if they're going canon with his look --- he might wind up being Hulk-sized after all.
Triple A filmed those scenes with Odin and Frigga, presumably looking something like what we've seen in the Malekith and Company pics, since Algrim is just another Dark Elf; but I'm beginning to suspect we won't see any images of Kurse until post, where he'll show up as a CG construct.
