Justice League actor Ray Fisher has accused director Joss Whedon of "gross, abusive, unprofessional, and completely unacceptable" behaviour on the set of the superhero movie.
Whedon, 58, took over duties on the film, which was widely panned by critics, from director Zack Snyder after he was forced to step down due to the death of his daughter.
Fisher, who played Cyborg, called out Whedon in a tweet on Wednesday, also alleging that Warner Bros' Jon Berg and DC's Geoff Johns had "enabled" the behaviour to continue.
"Joss Wheadon's on-set treatment of the cast and crew of Justice League was gross, abusive, unprofessional, and completely unacceptable," he wrote.
"He was enabled, in many ways, by Geoff Johns and Jon Berg.

Whedon, also known for Buffy The Vampire Slayer and The Avengers, has yet to comment on Fisher's allegations.
