JON Peters has been hit with a shocking new barrage of sex charges – this time by a male staffer who claims the powerful Hollywood producer of “Superman Returns” and “Ali” sexually roughed him up and threatened to break his legs.

In a lawsuit filed this week in Los Angeles Superior Court, Brian Quintana – a co-producer with Peters on the upcoming “Superman: Man of Steel” – alleges that Peters subjected him to “continuous and pervasive sexual harassment.”

The suit states there were “multiple instances where he was physically, sexually harassed by Peters, including being groped by male individuals at Peters’ behest.” Peters would “wrestle and rough up [Quintana] in a sexual manner . . . fondle himself in front of [Quintana] . . . often place his hand on [Quintana’s] leg in a sexual manner,” as well as “touch” his buttocks, the suit alleges.

In addition, according to the suit, Peters demanded that Quintana “drive male individuals onto the set for the purposes of granting sexual favors for members of the cast and crew [and] cover up allegations that . . . Peters engaged in sexually inappropriate acts in front of children.”

Quintana, in the court papers, also charges that Peters threatened to “break his legs” and fired him after he refused to “perjure himself” by signing documents stating that Peters had completed community service for a DUI conviction.

Peters, a one-time boyfriend of Barbra Streisand, is already being sued by two female former staffers who claim that he sexually harassed them. One, Blanca Hernandez, claims that Peters touched her breasts and buttocks, tried to push her onto his bed when he was naked, tried to kiss her breasts and offered her money for sex.

Peters’ office number has been disconnected. His lawyer, Stephen Kolodny, did not return calls yesterday.
