Set Video Suggests Intriguing Detail About Ezra Miller's Flash Costume

As work on "The Flash" continues in the U.K., set photos and videos tease what to expect from the Scarlet Speedster's first solo movie. DC fans recently got a look at Ben Affleck's Batman riding a stunning new bat-cycle on the set, suggesting that the Caped Crusader will do more than just mentor Barry Allen (Ezra Miller). The hero will even meet Michael Keaton's Batman from the 1989 movie.

The plot of the film is still being kept under wraps, but it seems quite ambitious. Warner Bros. is clearly using The Flash's time-traveling abilities to unite other DC movies into a cohesive continuity. Does that mean the DCEU will become the DC Extended Multiverse? Possibly. It would easily explain the three different versions of Batman that will be seen in 2022. Michael Keaton and Ben Affleck will both appear in "The Flash," while Robert Pattinson will lead "The Batman". They all live on different Earths. Problem solved.

Aside from multiple Dark Knights, "The Flash" will also introduce Sasha Calle as the DCEU's Supergirl — with previous set photos showing off her slick red and blue costume. And a new set video teases a surprising detail about Ezra Miller's costume in "The Flash."

The latest set video (via dcmarvel.rdm) shows the crew working in Waltham Cross, just north of London in the U.K., with Ezra Miller wearing the Flash's mask, gloves and boots over the top of a CGI jumpsuit. The video doesn't spoil anything too specific about the film, as Barry is obviously running into the scene, or out of it, but the motion capture markers on the outfit Miller is wearing makes it clear there are plenty of CGI elements in the new costume.

Director Andy Muschietti previously revealed the suit's iconic lightning bolt logo, confirming that there will be a practical costume. It's likely the production is using CGI just to add to the flashy spectacle of Barry's abilities. Fans quickly debated online that it might be used just to add lightning across the speedster when he runs. Some will remember the DC FanDome concept art for the film saw The Flash wearing a new suit next to Keaton's Batman. That suit had energy flowing across it, which is probably power from the Speed-Force, which gives Barry his abilities.

It will be well over a year before "The Flash" is released in November 2022, so it might be some time before fans get a trailer to confirm what the costume will look like in the finished production.
