Will Avengers: Doomsday be most expensive movie of all time?

With RDJ getting paid 100+ Million alone and Russo's getting paid 80+ Million just to direct these two movies and all the legacy characters returning, Doomsday budget will no doubt cross 500+ Million at minimum.

Most expensive so far at net is Star Wars: The Force Awakens costing 447 Million in production followed by Jurassic World: Fallen Kingdom at 432 Million

Most expensive MCU film at net is Avengers: Age of Ultron at 6th place with around 365 Million followed by Avengers: Endgame at 356 Million and then Doctor Strange in the Multiverse of Madness at 351 Million
