Kreisberg is the executive producer of 'Supergirl' as well as its fellow CW/DC Comics shows 'Arrow,' 'The Flash,' and 'Legends of Tomorrow.'
Another Hollywood executive has been fired following allegations of sexual harassment.
Warner Brothers Television Group confirmed to ET in a statement on Wednesday that Andrew Kreisberg -- executive producer of Supergirl as well as its fellow CW/DC Comics shows Arrow, The Flash, and Legends of Tomorrow -- has been fired from his show duties and has already been replaced.
"After a thorough investigation, Warner Bros. Television Group has terminated Andrew Kreisberg’s employment, effective immediately," reads the company's statement on the matter. "We remain committed to providing a safe working environment for our employees and everyone involved in our productions."
Warner Bros. also announced that Greg Berlanti -- who's already an executive producer on these shows -- will be picking up the slack following Kreisberg's termination.
"Greg Berlanti will assume additional responsibilities on both The Flash, where he will work closely with executive producer/co-showrunner Todd Helbing, and Supergirl, where he will work closely with executive producers/co-showrunners Robert Rovner and Jessica Queller," the company's statement also notes.
Those at Berlanti's production company -- which developed Arrow with Kreisberg -- also reacted to the exec's firing.
"Warner Bros. Television Group recently concluded its investigation into the allegations against Andrew Kreisberg. We encouraged and supported this investigation, we believe and support the individuals who came forward, and we agree with the studio’s decision," reads the statement. "Nothing is more important to us than the safety and well-being of all our colleagues, coworkers, crew and staff alike."
Earlier this month, Kreisberg was suspended from the shows following an expose in Variety where 19 people, who spoke on the condition of anonymity, accused the TV exec of sexual harassment. According to the report, Kreisberg is accused of creating a "toxic" work environment, which included touching people without their consent, making lewd and sexual comments about women's appearances, and making employees uncomfortable.
Not long after the allegations were made public, Supergirl star Melissa Benoist responded in a powerful post on Instagram. “I am a woman who leads a show that supports equality and feminism, empowerment, and fighting for what is right," she wrote. "When people are mistreated, they should have a safe forum to speak their truth and always be heard. And when people commit crimes or harass others, they should always be held accountable — no matter what industry they work in or how much power they wield."
The Flash stars Stephen Amell and Grant Gustin also addressed the accusations made against Kreisberg separately on social media.
During a Facebook Live session, Amell said he told his co-workers, "If anyone ever feels anything less than 100 percent safe, or anyone feels as though they aren’t allowed to express themselves and be the person that they are, that they should come to whomever they’re supposed to go to, and I’ll stand right beside them, right behind them. I’ll speak on their behalf if need be.”
As for Gustin, he took to Instagram to talk about the scandal. "Hearing of different men, again and again, especially in the industry that I work in, treating women as if they are less than, and both physically and emotionally abusing them has become a daily occurrence," Gustin wrote. "This is not OK. This can't become our new normal... I'm in awe of not just all the women who have spoken out these last few weeks, but any woman who has ever done so. I can't imagine how terrifying it must be and how much courage and strength it takes. These women are the real superheroes and they should be treated as such."
Meanwhile, the list of men in Hollywood accused of various instances of sexual misconduct appears to grow almost daily. Here's the latest on Matt Lauer's Today show ousting following claims of sexual harassment.
