According to a technical crew member on Captain America: Brave New World who was present on set and has knowledge of the film’s postproduction process, Disney is all too aware of its potential liabilities — on the heels of disastrous test screenings last year that necessitated a lengthy 22 days of reshoots, the 11th-hour addition of a new supervillain played by Giancarlo Esposito, major sequences being cut, and the film’s release date being punted from February last year. In particular, Harrison Ford’s Red Hulk/Thaddeus “Thunderbolt” Ross character created uncomfortable political resonances.
Compounding matters, Ford (now 82) lived up to his reputation as a legendary curmudgeon on set, according to the source, making matters more difficult for Onah — an acclaimed independent filmmaker but one, like so many hired by Marvel, with zero experience directing within the trappings of a nine-figure budget.
