There was a scene between Malekith and Odin that was cut out
Feige: “There was a showdown, and one of Malekith’s lines there was in the first trailer – he references sacrifices he’s had to make in the past, confronting Odin on what he’s willing to sacrifice, referring to Frigga, who’s at the end of a knife blade – but what happened was, and it was nobody’s fault except our own, really, was that we’d constructed a scene that was a mistake.
“Odin put down his spear, and Malekith successfully got Odin to put down his spear, and then kills Frigga anyway. And the early audiences went, ‘What the hell!? Why would he do that? Odin wouldn’t do that!’ They rioted in the seats. They took their pitchforks and tore up the seats. (Laughs)”
Taylor: “I spoke to Chris Eccleston yesterday, and he was saying that was the scene he missed most. You’ll get to see it on the Blu-ray, but as a part of getting this film more focused, in that particular case, you’re serving big things. Great work was done by all the actors, but frequently the most beloved things have to go.”
Feige: “We did a little bit of additional photography. The version you see in the movie was cut mainly from all the original version of the scene with an additional line here and there. It now has Odin entering afterwards. In other words, the audience could forgive him for being late, but they could not forgive him for wimping out and putting the spear down.”
“We do test screenings and the numbers do not dictate everything to us, but when they are overwhelming, you know something is going on – [but with the changes] they shot up. Suddenly people loved and respected Odin again.”
