Wonder Woman 2 will break new ground by being the first Hollywood film to use brand-new anti-sexual harassment guidelines from the Producers' Guild of America (PGA).
The guidelines, which were released on Friday ahead of Saturday's PGA Awards, recommend that every production "provides in-person anti-sexual harassment training for all members of the cast and crew". In excess of 2,000 people were involved in the production of the first Wonder Woman film.
The PGA says that this training "should not be simply focused on avoiding legal liability, but must be part of a culture of respect that starts at the top".
It urges producers to "be vigilant" and to make sure that the training doesn't end there: "Consider taking steps to maintain awareness of harassment on an ongoing basis."
Other suggestions include "designating at least two individuals, ideally of different genders" that workers can approach if they are subject to or witness harassment.
The document also has a section on "common misconceptions", where it states: "A hug, kiss on the cheek, or casual touch is not necessarily sexual harassment. The key is whether the behaviour was unwelcome or offensive."
This isn't the first time that members of the Wonder Woman team have taken a stand against inappropriate behaviour in Hollywood.
Star Gal Godot made headlines last November when she reportedly threatened to pull out of the sequel if she had to work with then-producer Brett Ratner, who has been accused of sexual misconduct. The X-Men director went on to "step away" from Warner Brothers and the project.
The controversy came just weeks after the PGA voted unanimously to expel scandal-hit mogul Harvey Weinstein, and began working on these new anti-harassment recommendations for their 7,000 members.
The recommendations and the fact that they have been adopted by a major blockbuster like Wonder Woman 2, seem to be part of a sea change in Hollywood's attitudes towards sexual misconduct.
The PGA has pledged to work with the Time's Up campaign, which saw stars wore black on the red carpet at the Golden Globes earlier this month to highlight abuse.
In a joint statement, the PGA's presidents, Gary Lucchesi and Lori McCreary said: "Sexual harassment can no longer be tolerated in our industry or within the ranks of the Producers Guild membership," and added that it was the obligation of producers " to change our culture and eradicate this abuse".
