Actresses Olivia Munn and Natasha Henstridge both spoke to the Los Angeles Times about their experience with Brett.
Olivia, now 37, alleges that in 2004 Brett visited her trailer on the set of After the Sunset - a film he was directing - where he masturbated in front of her.
"He walked out... with his belly sticking out, no pants on, shrimp cocktail in one hand and he was furiously masturbating in the other," she recounted.
"And before I literally could even figure out where to escape or where to look, he ejaculated."
Natasha recounted a story from when she was 19, telling the publication that the Rush Hour director forced her to perform oral sex on him at his New York apartment after watching a movie with a group of friends.
The Los Angeles Times article, which was published on Wednesday, has a total of six women speaking up about their traumatising experience with the 48-year-old.
Brett Ratner's attorney Martin Singer has vehemently denied the report, saying, “no woman has ever made a claim against him for sexual misconduct or sexual harassment. Furthermore, no woman has ever requested or received any financial settlement from my client.”
Who is Brett Ratner?
Many would recognise Brett's work from movies like the Rush Hour series and Jennifer Aniston's Horrible Bosses.
The director/producer is also set to make the biopic on the late Playboy founder, Hugh Hefner, with Jared Leto in the starring role.
Brett has dated the likes of Paris Hilton, Mariah Carey and Lindsay Lohan.
He is also good friends with Jame Packer and together they created RatPac Entertainment - a film production company.
Meanwhile, The Hollywood Reporter shared Anna Graham Hunter's first-person account of her time as a 17-year-old production assistant on the 1985 film Death of a Salesman, starring Dustin Hoffman.
She wrote about that Dustin, now 80, was among the many stars who she received attention from - but it was the actor who touched her inappropriately and used sexually explicit language with her.
"And yes, I loved the attention from Dustin Hoffman. Until I didn't," Anna wrote.
Anna had kept copies of letters she wrote to her sister at the time.
During her five weeks on set, Anna recounted unwelcome comments and touching from Dustin.
"Today, when I was walking Dustin to his limo, he felt my ass four times. I hit him each time, hard, and told him he was a dirty old man," she'd penned in a letter dated on January 31, 1985.
Dustin has since responded to the allegations.
"I have the utmost respect for women and feel terrible that anything I might have done could have put her in an uncomfortable situation. I am sorry. It is not reflective of who I am," he said in a statement.
