Andrew Kreisberg may not be a household name, but he has been responsible for a number of the CW network's best performing series in recent years. As the executive producer of major superhero shows like "Arrow," "The Flash," and "Supergirl," the 46-year-old showrunner controlled some of the hottest titles on the teen network. Unfortunately, that all came crashing down on Friday (Nov. 10) after nearly 20 people who worked on his shows came forward with allegations against him.

Suspended, pending investigation

Warner Brothers Television -- the studio behind all of the series Kreisberg had been most recently attached to -- announced late Friday evening that they have launched an internal investigation into the slew of allegations against the producer.

Kreisberg has been suspended from working until that investigation is concluded. There has yet to be any information on how such an investigation might impact those shows currently in production.

15 women and four men have alleged to Variety that staff endured Sexual Harassment and inappropriate physical contact while working for the producer. Allegations include unwanted touching by Kreisberg, non-consensual kissing, and asking for massages from female staffers. Prior to producing superhero fare for Warner Brothers, Kreisberg had been a writer and producer on hit shows such as "Boston Legal," "The Vampire Diaries," and "Fringe." As the victims who have come forward all did so anonymously, it is not known which series they may have worked on.

Latest embattled Hollywood exec

Kreisberg is only the latest in what has become a near-daily naming of Hollywood actors and executives who have allegedly used their position of power to carry out sexual misconducts against others.

Both Harvey Weinstein and Kevin Spacey are reportedly seeking treatment at the same rehabilitation facility in Arizona after allegations against each of them reached the double-digits.

Director Brett Ratner is facing such fierce backlash against his admitted history of sexual harassment against women that "Wonder Woman" star Gal Gadot is reportedly refusing to commit to a franchise sequel until his RatPac Entertainment company is removed as a producing partner.

Even 80-year-old "Star Trek" actor George Takei was accused of sexual assault this past week, with former model Scott R.

Bruton telling media that he was groped in the actor's apartment in 1981. Takei responded to the allegation in a series of Tweets, claiming he did not know Bruton.
