For so many genre fans out there, The CW’s DC-driven output of Arrow, The Flash, DC’s Legends of Tomorrow, and Supergirl is part of their must-see weekly viewing habits. Well, the network has now moved to fire one of the key minds behind this shared televisual realm.

Executive producer Andrew Kreisberg, who helped develop all four of the aforementioned shows from the get-go, has been fired by Warner Bros. TV Group following investigations into multiple allegations of sexual harassment. Recently, Kreisberg had been suspended by the network, and now the decision has been made to terminate his contract after fifteen women and four men across the various DC shows made allegations of sexual harassment and inappropriate physical contact.

In a public statement, the network said, “After a thorough investigation, Warner Bros. Television Group has terminated Andrew Kreisberg’s employment, effective immediately. 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. We remain committed to providing a safe working environment for our employees and everyone involved in our productions.”

Greg Berlanti and Sarah Schechter also released a statement, adding, “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. Nothing is more important to us than the safety and well-being of all our colleagues – co-workers, crew and staff alike.”
