The Flash will be ending with its upcoming ninth season on The CW.

This final season will most likely serve as the end of a chapter for the network's Arrowverse of shows.

Considering the timing of things — could the final season of The Flash show dovetail directly into the upcoming The Flash movie?

Miller made a secret cameo in The CW's "Crisis on Infinite Earths" crossover. 

In the weeks that followed that episode, it became known that Warner Bros. itself had requested for Miller's cameo to be included, and that The Flash movie writer Christina Hodson had "planned" for it when writing the film.

Well,the Flash movie is scheduled to be released in theaters on June 23, 2023.
