Thor (2011)

Loki's most interesting weapon in Thor is the pause before he tells another person what they want to hear. Tom Hiddleston makes the younger brother's desire for recognition visible inside a controlled public manner. Chris Hemsworth gets the more straightforward passage from arrogance towards responsibility; Loki keeps changing what his apparent restraint means. This is his antagonistic role in the 2011 film, rather than a judgement imported from later adventures.
