How Justice League Filmed Flash's Speed Force Scenes


Justice League is approaching faster than The Flash, and as we get closer to its release, more is being revealed about how some of the film's jaw-dropping scenes were filmed.

In an interview with Fox 5's Kevin McCarthy, the Justice League cast discussed the mechanics of Ezra Miller's slowed-down, super speed scenes. "Sometimes they shoot them with high-speed cameras so the action actually slows down," Ben Affleck explained, referring specifically to the trailer shot of his Bruce Wayne throwing a batarang past Miller's Flash. "We brought in for that day special cameras that shot at a high frame- rate so that I just threw [the batarang] full-speed... then you shoot Ezra at a slightly different frame rate so that it looks a little bit slow but also that he's moving faster than I am." Affleck explained that viewers can tell the two were shot on different cameras "if you watch it carefully." Watch the full interview below:

Ray Fisher, who portrays Cyborg in the Zack Snyder/Joss Whedon-directed blockbuster also talked about filming scenes where characters were frozen during Barry's high speed hijinks. "The VSFX crew and Zack, they worked out the physics of that speed force and what we should be doing."

McCarthy later interviewed Gal Gadot and Miller on his favorite scene- another moment from the trailer where The Flash runs ahead and essentially boops Wonder Woman's Godkiller sword. The scene involved an elaborate forklift/harness situation for Gadot, but was apparently simpler for Miller. "All I had to do was run. They hung a sword from the ceiling."

Miller previously spoke about filming his end of the Flash's scenes, which apparently involves a large, elaborate treadmill of sorts. "“It’s pretty much a dream come true," Miller said. "And then they strap me into a harness — we do all sorts of stuff.”

Starring Ben Affleck as Batman, Gal Gadot as Wonder Woman, Henry Cavill as Superman, Amy Adams as Lois Lane, Jason Momoa as Aquaman, Ezra Miller as The Flash, and Ray Fisher as Cyborg, Justice League hits theaters November 17.
