Hiddleston told fans at ACE Comic Con that the entire “get help” concept was conceived of on the same day it was filmed.
“I think
that the one that’s kind of had its own life after the film is ‘get
help,’” Hiddleston said. “We literally just came up with it on the day.
As something, this idea that this is a trick that Thor and Loki used to,
you know, they used to use it as a game when they were kids and they
stopped doing it a long time ago but it used to work and it might just
work this time. They’ve got one last ace up their sleeve. And the idea that
Loki hated it, and just was like, ‘I don’t want to do it. It’s
humiliating. And that Thor was like, ‘You’re going to love it! Come on!’
in a big brother way. And then it works. In that moment, I always love
the fact that it wasn’t just a funny moment, but actually, you
understand something deeper about them as brothers, and I think those
moments are really special.”
