Skyrim movie fancast?

If there was a movie of Skyrim, who would you choose to be the “main characters” (dragonborn, greybeards, partysnacks, Delphine, balgruuf, hadvar, tulliess, ulfric, Serana, Lydia, etc) including dlc. I think it would be hard to get people who actually looked like the characters, but even harder to get someone who sounded, and acted like them, who would you fancast?
