The DC Extended Universe is slowly working to build its next exciting slate of in-universe films while Zack Snyder's Justice League makes its impressive run on HBO Max. Included in this next bunch of projects will be sequels and origin stories alike, including one of the most oft-delayed films of the entire franchise in The Flash.

Originally meant to release just after Justice League in 2018, The Flash has seen multiple directors enter and exit the production, with the same thing happening in the movie's cast as well. This has been the case in the last couple of weeks alone with Kiersey Clemons rejoining the movie as Iris West while Billy Crudup left the role of Henry Allen, which he played in both versions of Justice League.

The most recent news surrounding this movie not only finds Crudup's replacement but also adds three new names to the team.


Variety is reporting that actor Ron Livingston is joining the cast of Warner Bros.' The Flash as Henry Allen. He replaces Billy Crudup, who recently left the project due to scheduling conflicts.

Additionally, Ian Loh will be playing the young version of Barry Allen in the film. The call sheet also lists undisclosed roles for Derry Girls star Saoirse-Monica Jackson and internet personality Rudy Mancuso.


With the production start date finally drawing closer for this long-awaited DCEU solo movie, this comes as exciting news on the casting front.

Livingston is best known for playing the lead role in the 1999 cult classic Office Space, and he holds a recurring part in the currently running hit TV show A Million Little Things on ABC. While it's unclear how expansive his role will be in The Flash as Henry Allen, he should be key in helping give depth to Ezra Miller's hero backstory.

The same can be said about Ian Loh, who will help show Barry Allen's earliest days, likely long before he becomes the fastest man on Earth. It will be interesting to find out Jackson and Mancuso's roles when the time comes, but it's clear that things are finally gearing up for this solo film to begin coming to life.

The Flash is set to begin filming on April 26, and it will release in theaters on November 4, 2022.
