Interesting Behind the Scenes Story Regarding the Filming of Dr. Strange 2 and the Illuminati Scene with all of the Different Actors. This is from an Anson Mount interview, the actor who portrayed Black Bolt in the scene and stars in the Star Trek franchise when asked if he met fellow Star Trek actor Patrick Stewart.
"No, he was actually not there! [Laughs] He was shooting Picard. That was a very interesting shoot because my role came up in the reshoots. As you can imagine, several of the actors were quite busy. Patrick was not there. Chiwetel [Ejiofor] was not there. Krasinski's contract wasn't even done. He wasn't there. We had actors playing those roles, knowing that they were going to either be substituting their shots or transplanting faces. I've never done anything quite like that, and I was in disbelief of how well it cut together."
Apparently, most of the Illuminati wasn't even there. Or at least half of them. Which is kinda crazy but the scene was very well edited regardless since it didn't even occur to me. This might explain why some of the Heroes got fragged while others got a more prolonged fight scene perhaps...
