The Flash costume was one of many topics that Ezra Miller talked about alongside Cyborg actor Ray Fisher during their panel at Wizard World Portland this past weekend.
While Miler’s Flash suit doesn’t look nearly as cumbersome as the bulky Batman suit Ben Affleck has to wear, it didn’t look like it was particularly comfortable to wear, but evidently once the costume designers made the appropriate changes, Miller was not only to move around more freely, but also appreciated how much work went into the suit’s creation.
Although Miller officially debuted as Barry Allen in Batman v Superman: Dawn of Justice, he wasn’t seen wearing the Flash’s classic suit until his cameo in Suicide Squad, and the suit was put to full use in Justice League over a year later.
