The 20-year-old, who is new to the acting industry, is said to have been left devastated by the film, which features interviews with two men, James Safechuck and Wade Robson, who claim they were s-xually abused by her father when they were children.
It's said Paris has told friends that she's worried the film will put movie bosses off from casting her over fears it's all anyone will talk about.
A source told The Sun : "Paris had hoped to launch a successful career in acting but fears Leaving Neverland has ruined her chances of it taking off.
"She was in a movie last year but believed the documentary is already scaring directors away because the abuse her father is accused of may put movie-goers off her.
"It all comes down to marketing. The worry is that any movies she stars in will be derailed if Michael's abuse scandal is all people think about when they see her on screen. She wants to act but knows this could affect those plans."
