DC's upcoming "Flash" feature film hit another speed bump when it lost director Rick Famuyiwa. The director, known for the acclaimed film "Dope," parted ways with the Warner Bros. superhero film in late October citing creative differences with the studio. This is the second time the film has lost a director, as Seth-Grahame-Smith (“Pride and Prejudice and Zombies”) left the project earlier this year.

While speaking with CinemaBlend, "Flash" star Ezra Miller -- who's been attached to the film since it was announced in 2014 -- revealed what he thinks the film's director needs.

"I think that the most important quality is the open heart," said Miller. "I think that The Flash has to be a story that is heartfelt. Because I think that's where the lightning really is."

Prior to Famuyiwa's departure, Seth Grahame-Smith left the project in April of this year, also citing creative differences. The same also happened with "Wonder Woman," when original director Michelle MacLaren departed the picture in April 2015 also citing creative differences.

While "The Flash" has yet to begin production, Miller's already appeared twice as the big screen version of the Scarlet Speedster. He had a cameo appearance in "Batman v Superman: Dawn of Justice," both in a vision had by Bruce Wayne and security camera footage showing him using his powers. He then appeared in a vignette in "Suicide Squad" wherein he quickly apprehended Captain Boomerang.

"The Flash" is currently slated to arrive in theaters on March 16, 2018, although it's not yet known if that date will be pushed back following the departure of Famuyiwa. While it's not been clarified if the film's release date is being pushed back or not, it's been reported that it will shoot in fall 2017 as opposed to early 2017.

“The Flash’s” cast includes Ezra Miller (“The Perks of Being a Wallflower”) as the Scarlet Speedster, Kiersey Clemons — who previously worked on “Dope” with Famuyiwa — as Iris West, Billy Crudup (“Watchman”) as Barry Allen’s father, Henry Allen, and Ray Fisher (“Batman v Superman: Dawn of Justice”) as Cyborg.
