Yeah, but would it be worth the cost? Bloated budget and reshoots might eat into profits even further - or just make the losses worse. Best to just release it as is, quietly recast afterwards, and pray to whoever it is WB pray to. I used to think it was the All Mighty Dollar, but you'd think they'd be smarter about making money if it was.
Plus there's precedent here they might want to avoid. If they reshoot Flash, they have to make back the money that went into the reshoot, AND make back the money that went into the original, unreleased Flash with Miller. This famously happened with Superman Returns, when it had to recoup its own production costs as well as the production costs of the Tim Burton Superman movie with Nic Cage. It was only, what, 60% finished and Superman Returns still had to recoup both (its own + Burton's), this would have to do the same. In fact it would be worse since the movie is already completed. 60% was impossible to clear, 100% wouldn't be easier.
Ezra Miller Arrested AGAIN in Hawaii, Fired from The Flash? Will Smith, Johnny Depp Comparisons
Agreed. You'd have to remount production, pay additional money in rehiring cast and crew, redo promotional material, redo effects from the ground up etc. It just isn't cost effective to reshoot it now. I guess they could just shoot another actor against green screen and digitally insert them into pre-existing shots... but does anyone want that?
No. Best to do as you suggested. Reshoot another, singular scene with another actor taking over as the flashpoint resets.
