The second trailer for the Thor sequel, Thor: The Dark World.
I really rather like that slap and Loki's response to it.
Hell, I like every second of Tom Hiddleston in that trailer. He clearly has so much fun playing the character of Loki, as evidenced by his Comic-Con appearance, and all that positive energy really makes his character stand out.
Thor: The Dark World will arrive in the UK on the 30th of October and in US cinemas on the 8th of November.
