Lawsuit Accuses Bryan Singer of Sexually Assaulting 17-Year-Old Boy

Cesar Sanchez-Guzman is suing Bryan Singer, alleging sexual assault.

Sanchez-Guzman's attorney, Jeff Herman, filed a lawsuit Thursday againstthe Usual Suspects director. Sanchez-Guzman claims Singer claims raped him in 2003, when he was 17.

Singer was at a Seattle-area party on a yacht owned by tech investor Lester Waters. The majority of guests were young gay males, including the plaintiff, according to the suit.

At the party, Singer allegedly met the teenager, and offered to give him a tour. Then, Singer "lured Cesar into a room, shut the door and demanded that Cesar perform oral sex," as described in a press release from his attorney.

When Sanchez-Guzman refused, the bisexual producer allegedly forced him into acts of anal and oral sex, as Sanzhez-Guzman pleaded with him to stop, according to the suit.

Afterward, the suit claims, Singer contacted Sanchez-Guzman to dangle the promise of a Hollywood career in exchange for his silence. Singer allegedly also warned Sanchez-Guzman that if he came forward with his story, he would not be believed, and that Singer had the resources to ruin him.

Through a representative, Singer denied the allegations. "The lawsuit was filed by the same lawyer who represented Michael Egan. Those claims were dismissed by Egan himself, and he later went to Federal prison for lying in a fraud case," the rep told TMZ.

Previously, Herman did represent Egan, who accused Singer and other Hollywood bigwigs of sexual assault. The suit was dismissed, and Herman offered an apology to several of the accused for "false allegations" (but not Singer).

Herman, who specializes in cases involving victims of sexual abuse, is also representing actress Dominque Huett, who says she was sexually assaulted by Harvey Weinstein. She is suing the Weinstein Co., alleging it enabled his behavior, according to The Hollywood Reporter.Herman's website lists many cases he has won for his clients, but he also has some blots on his record, having been "suspended by the Florida State Supreme Court and barred for life by an Oregon federal judge," the Reporter notes. He has dismissed these as "irrelevant."

This is not the first time Singer made headlines this month. He was fired from a production of a Queen biopic starring Rami Malek as Freddie Mercury, amid reports of erratic behavior. He allegedly clashed with Malek on set and at times did not show up to work. One source claimed Singer is suffering from post-traumatic stress disorder.
