If CM opens to 150MM+ (looking likely right now), then:
Worst OW MCU domestic multiplier(2.28 CW) = 342MM
Worst OW MCU domestic multiplier origin movie (2.43 TIH) = 364.5MM
Average MCU domestic multiplier for first movie in series (2.96) = 448MM
Average MCU domestic multiplier (2.76) = 414MM
While I don't want to say 400MM is a lock because I need to see the WOM first, I think this movie will probably get a 2.75 - 3+ multiplier, especially since it has no competition until Us. If the 150MM OW holds I'm guessing it will outgross Diana in the US and become #2 origin solo movie debut.
