>>212438080Yeah Ezra was frustrated with WB dragging its feet on getting Flash up and running and didn’t agree with what they wanted for the movie so he sought out Morrison to write that original screenplay together in 2018.
But then his original contract was going to expire May 2019, so an ultimatum was made where either WB accepted Morrison/Ezra’s script or he was going to walk away/be recast
In the end the compromise was they kept Ezra/renewed his contract and hired Andy M. and Christina Hodson, who wrote a new script that was based partially on the old script Ezra didn’t like but with the multiverse elements added (Daley and Goldstein retain a “Story By” credit on the movie)
