Co-creator and executive producer of the CW’s DC Comics series The Flash, Supergirl, Arrow, and Legends of Tomorrow Andrew Kreisberg has been suspended from his duties by producer Warner Bros. Television Group following allegations of sexual harassment. According to Variety, Kreisberg has been accused of engaging in a pattern of alleged sexual harassment and inappropriate contact for years, which are based on the accounts of 15 women and four men who worked with him. The studio stated that they are launching an internal investigation into these accusations.

Warner Bros. TV Group stated to Variety, “We have recently been made aware of allegations of misconduct against Andrew Kreisberg. We have suspended Mr. Kreisberg and are conducting an internal investigation. We take all allegations of misconduct extremely seriously, and are committed to creating a safe working environment for our employees and everyone involved in our productions.”

Greg Berlanti and Sarah Schechter, who head Berlanti Productions, which oversee the CW/DC shows, stated, “We were recently made aware of some of the deeply troubling allegations regarding one of our showrunners. We have been encouraging and fully cooperating with the investigation into this by Warner Bros. There is nothing more important than the safety and well-being of our cast, crew, writers, producers, and any staff. We do not tolerate harassment and are committed to doing everything we can to make an environment that’s safe to work in and safe to speak up about if it isn’t.”

Kreisberg has denied the allegations with telling Variety, “I have made comments on women’s appearances and clothes in my capacity as an executive producer, but they were not sexualized. Like many people, I have given someone a non-sexual hug or kiss on the cheek.”

The accusation regarding Kreisberg’s behavior include frequently touching people without permission, kissing women without their consent, and asking female staffers for massages. None of the complaints against Kreisberg were reported to human resources at Warner Bros. in fear of retaliation from the company.

One woman explained, “Going to HR never crossed my mind, because it seems like nothing’s been enforced.”

These claims also stated that Kreisberg created a “toxic” and hostile work environment for many women, claiming that he makes “the workplace unsafe.”

Kreisberg denies these claims saying, “I have proudly mentored both male and female colleagues for many years. But never in what I believe to be an unwanted way and certainly never in a sexual way.”

It is unclear if production on any of the CW/DC shows will be impacted in any way since all of them are currently in filming.
