Daley and Goldstein, whose recent works include "Spider-Man: Homecoming" and "Game Night", "have a light-hearted approach to the material," according to hollywoodreporter.com.
On the other hand, Miller wants a darker take on the material.
Generally, the light-hearted approach is favoured by Warner Bros., which has experienced success with "Aquaman" and is seeing strong buzz with the upcoming "Shazam!".
Both movies take on the fun route, with the latter infusing more humour.
In a bid to keep himself involved in the movie, which is reportedly called "Flashpoint", Miller is teaming up with Grant Morrison, the acclaimed comics author, to rewrite the script.
It's reportedly the actor's initiative to tackle the story himself, after their attempt to compromise last year didn't lead to an agreement.
While Miller is said to be deeply committed to the role, there's a possibility that the actor will leave the project should the studio go with Daley and Goldstein's version and forgo Miller's take on the superhero.
Miller's contract on "Flash" will reportedly expire in May.
