To be fair it's not out of place as the movie version of Loki actually behaves like this. He can be evil grinning and jolly one second and then be dead/angry serious the next and back and forth again all the time. If you watch the Avengers conversations between him and Widow or Stark he switches moods about 5 times in both of those scenes alone.Teoes said:I think he slipped out of character, just a teeny bit, when it got a bit too much. There was a laugh that was Tom Hiddleston chuckling at how boss he was being before he went back to gnawing the set.

I guess it part of the "madness" of his character.
