Entirely. I think Loki grows up with an older brother who he loves and respects. They play, they banter and they bash each other about, but there is a latent jealousy. Craig Kyle – one of our producers – always used to talk about the analogy of the quarterback and the artist. Thor is the quarterback. He’s a chip off the old block and he’s just like his dad. Loki’s problem is, maybe not his problem, but [that] he’s more drawn to the powers of intellect, magic, and the dark arts.

He’s not going to be out in the fields throwing a hammer around. That’s just not where his passion lies. There’s a disconnect with Odin and there’s a disconnect with Thor. He loves them very much, but he’s not just made of the same stalk. In the course of the film there’s a big reveal both for Loki and the audience about the truth of Loki’s true lineage and who his real parents are. I think that begets any jealous that was within him towards Thor develops into a dark, cancerous rage that then becomes a destructive rage.
