Sylvester Stallone recently found himself at the center of controversy following allegations of fostering a 'toxic' environment on the set of his latest project, Tulsa King.

In response to his remarks, the actors' union SAG-AFTRA has stepped forward to note that “disparaging comments” directed at background actors would not be permitted.

The union shared the statement, “There is no room on any set for disparaging comments to background actors or any performers.”

It is added it the statement, “Though we have not been contacted directly about the incident on set of Tulsa King in Atlanta, SAG-AFTRA is committed to the safety and well being of cast members on all productions.”

Although "the Union's TV/Theatrical agreements do not cover background actors" in Atlanta, a spokeswoman for SAG-AFTRA acknowledged that the organisation does occasionally represent background performers.

TV writer Julie Benson's since-deleted X post from April 8 revealed the allegations against Stallone, which surfaced during the show's second season filming in Atlanta. 

The post read, “Got this disturbing news from my Atlanta friend who’s background on Tulsa King this wk,” adding, “Casting agent quit because she was so disgusted. My friend is feeling anxious about working now.@TheSlyStallone what do you have to say for yourself, sir? Beyond disappointed, I’m livid.”
