Hollywood movies are almost always all about the special effects. In superhero movies, it's hard to not really go with CGI, particularly when you're battling metahumans or perhaps showing off a cool power or two.
Following what we've seen with The Flash on TV, many may have thought that they'd be seeing Ezra Miller's portrayal of the Scarlet Speedster in roughly the same manner—that is, barely seeing him running with all that fast-forward running effect.
Apparently, we're wrong. Miller shared in an interview (via CinemaBlend) that filming The Flash actually entailed a treadmill. And actual running.
"Sometimes they make me run, which I was outraged, because I thought you know, playing The Flash will be great, because you can't see him running, so this is going to be easy. They were like, ‘No, no, Ezra, we need you to run."
Miller explains that he did this using a 25-feet worth of treadmill that can go as fast as 45 miles per hour. Since the actor can't possibly go at that kind of speed for a while, he added that he was strapped to a harness for better filming.
This better filming, it seems, makes use of both choreography and visual effects. He also mentions that there will be moments featuring The Flash's perception, so perhaps we can guess that it may be similar to how we felt when X-Men's Quicksilver was doing his thing saving everybody in slow motion.
This sounds very cool and all, if not for the looming issue of The Flashhaving two director exits and with no new named director tagged to the film as of yet. Hopefully, the vision for which Miller seems very excited about will still come to fruition even with a new director onboard.
If nothing changes as planned, The Flash should arrive in theaters on March 16, 2018.
