Doctor Strange in the Multiverse of Madness underwent extensive reshoots, though it was previously reported that the main purpose of this additional photography was to add even more high-profile cameos. With a confirmed runtime of 2 hours and 6 minutes, the sequel definitely isn't going to be bloated, though we wouldn't be shocked if Marvel Studios struggled to crack that Multiverse concept.
Even with an experienced filmmaker like Sam Raimi at the helm, it sounds like the production hit a few bumps in the road, which is something Bruce Campbell hinted at in a recent interview with Game Informer when he talked about Raimi's unique experience working with Marvel Studios.
"The Marvel guys, they make eight of these movies at the same time, so they're always updating storylines," the actor explained. "So, my buddy Sam [Raimi] has had to add scenes that [Marvel] told him he had to shoot, and he's removed scenes that no longer apply. So until May rolls around I don’t think Benedict Cumberbatch even knows if he’s in this movie or not."
Campbell is likely referring to the fact that he was, at least at one time, set to make a cameo appearance in Doctor Strange in the Multiverse of Madness. Rumour has it [SPOILER WARNING] that he had been cast as Balder, a member of the Illuminati. However, it's widely believed that the actor has been cut in order to make room for a higher-profile, potentially fantastic Variant.
Eternals proved that Marvel Studios isn't immune to the wrath of critics, so you have to believe they've gone to great lengths to ensure this movie doesn't disappoint.
Doctor Strange in the Multiverse of Madness is set to be released in theaters on May 6.
