Factual error: In the final fight scene with Malekith, Thor falls through a portal that brings him to Charing Cross station, where the lady on the train tells him he has to ride 3 stops to get to Greenwich. Charing Cross is not on the Jubilee Line and so not directly connected to Greenwich - even then it's a lot more than 3 stops. (01:33:45)
Continuity mistake: Sif has a wound on the left side of her forehead which disappears when she arrives at Asgard.
Question: Loki (as Odin) quotes a conversation that occurred between Thor and Odin. This conversation happened after Loki let go of the handle Thor offered to keep him from falling off the bi-frost. How does Loki know what Odin tells Thor when he's supposedly headed to Midgard (Earth) as they speak? Can Loki read minds? If so, I don't recall any movies he comes out in mentioning mind reading.
