Bryan Singer has been denied his initial request to dismiss a court case accusing him of raping a 17-year-old boy and forcing him to perform oral sex.

The X-Men director has denied the claims that he sexually assaulted Cesar Sanchez-Guzman on tech investor Lester Waters' yacht in Seattle in 2003.

Last month, Singer filed court documents demanding the case be thrown out, claiming he was never served papers in the lawsuit.

Guzman's lawyers claim that the documents were served to Singer's Los Angeles house and taken by a man named Peter Murphy, who said he lived at the home and had a 'close relation' with the director.

On April 20, a judge denied Singer's motion to dismiss and ordered the case continue in court, according legal documents exclusively obtained by DailyMail.com.

The court entered an order denying the motion to dismiss the case without prejudice to it being refiled, however, which means Singer's legal team have filed another request to dismiss over a second attempt to serve the director.

Singer's legal team have claimed the second attempt to serve the director was also invalid.

The second motion to dismiss the case is still pending, and the court will hear it in June.

Last December, Sanchez-Guzman's attorney filed court documents accusing Singer of sexually assaulting his client.

The lawsuit claims that Singer offered to take a then-17 Guzman on a tour of the yacht, but when they got to one of the rooms, the director allegedly forced the teen to the floor, shoved his crotch against Guzman's face and demanded he perform oral sex.

Guzman claims in the suit that Singer then pulled out his penis and forced it into his mouth, causing him to choke as he begged him to stop.

Singer allegedly forcibly performed oral sex on Guzman, who repeatedly told him to stop, before he anally raped him, according to the lawsuit.

The suit states that Singer later threatened Guzman, telling him he was a powerful Hollywood producer and that he could hire people to ruin his alleged victim's reputation.

He added that no one would believe him if he did come forward. But if he kept quiet, he would help his acting career.

Singer has denied the accusations and claimed he was never served documents in the lawsuit, asking that the case be thrown out.

Sanchez-Guzman said that he did serve the director and that a process server went to his Los Angeles home in January.

The server said the home is surrounded by a tall metal wall that prevents the public from gaining access.

He said that he tried to use an intercom to speak to someone and gain entry to the home, but no one responded.

At that point, the server 'stood up on the bed of a pick up truck next to the property' in an attempt to 'see over the wall', according to legal documents.

The server said he shouted Singer's name until someone opened the front door of the house and asked who he was.

When the server said that he was there to deliver paperwork to Singer, the man identified himself as Peter Murphy and said he also lives at the house and 'helps take care of the premises'.

The server, Pradip Kissoondyal, said that Murphy was around 30 years old and said he had a 'close relation' to Bryan Singer

Singer's lawyer, however, said in an email that 'No one by the name of Peter Murphy resides at Mr. Singer's home'

'He agreed to accept the documents and instructed me to 'come to the entryway on the right side of the property',' the server said in court documents.

The server said he handed Murphy a summons, jury demand, order setting case schedule and complaint.

The relationship between the Murphy and Singer remains unclear, but Murphy told the server that he is a 'close relation to Bryan Singer'.

Singer's lawyer, however, said in an email that 'No one by the name of Peter Murphy resides at Mr. Singer's home'.

In legal documents demanding a dismissal, the lawyer accused the server of not delivering documents to the home at all.

Then on April 20, a judge denied Singer's motion to dismiss and ordered the case to continue.

Guzman is suing Singer for emotional distress, mental anguish, and physical and mental pain.

A rep for Singer told People last year: 'Bryan categorically denies these allegations and will vehemently defend this lawsuit to the very end.

'Cesar Sanchez-Guzman apparently claims that he did not remember this alleged incident from 2003 until now. Significantly, when Sanchez-Guzman filed for bankruptcy only a few years ago, he failed to disclose this alleged claim when he was supposed to identify all of his assets, but conveniently, now that the bankruptcy court discharged all of his debts, he is able to recall the alleged events.'

The lawsuit was filed just days after Singer was fired from the upcoming Freddie Mercury biopic Bohemian Rhapsody.

He had just taken an unexpected leave of absence a few weeks before filming was set to wrap on the project, leaving Twentieth Century Fox in the lurch.

The decision to fire Singer came after the director reportedly feuded with multiple actors on the set according to The Hollywood Reporter, forcing Twentieth Century Fox to remove him from the project.

The director issued a statement attempting to clarify his sudden dismissal and blamed Fox for terminating his contracting despite him wanting to return to the US to visit a sick parent. He also hit out at Twentieth Century Fox, saying the production company was 'unwilling to accommodate' him in his situation.

But according to Radar, Singer regularly went on late night benders turned into crippling hangovers and threw tantrums on set that made him infuriating to work with.

An insider told Radar that the 'straw that broke the camel's back,' was when the studio asked Singer if there were 'going to be any allegations dropping on him.'

New claims against Singer began to emerge in the wake of the Harvey Weinstein sex scandal, and MeToo campaign, including allegations made one young man who said that the director touched him inappropriately over a decade ago.

The thread detailing that claim was taken off Twitter however and the user's profile deleted, while a story on Yahoo about the allegation was taken offline.

At the same time, a tweet by Evan Rachel Wood referencing past allegations against Singer was taken off the actress' account, much like a comment from actor Noah Galvin was removed in 2016 from an interview in New York.

Galvin later issued an apology for his comment, stating: 'My comments were false and unwarranted.'

In a 1997 accusation, a 14-year-old boy filed a lawsuit claiming that he and other minors were asked to strip naked while filming a shower scene for the film Apt Pupil, which was directed by Singer.

Two more teens would come forward to support his claim, but the suit was ultimately dismissed for insufficient evidence.

Michael Egan made accusations against Singer in his own 2014 lawsuit, which claimed he began being sexually abused when he was 14 or 15 after moving to Los Angeles with his family to start his acting career.

It was in LA that he was introduced to Hollywood powerplayer Marc Collins-Rector and his lover Chad Shackley when he was invited to a party at Collins-Rector's home.

These parties allegedly 'featured sexual contact between adult males and the many teenage boys,' according to Egan, but he maintains he 'never freely' consented to the advances.

It was two or three months after Collins-Rector began allegedly abusing Egan that he was introduced to Singer at one of the parties he claimed in his lawsuit.

Egan said he was in the pool, and nude, when Collins-Rector approached him and ordered him out to hug Singer, who allegedly grabbed his bare buttocks.

He claimed Singer later said he was 'sexy' and went on to masturbate the underage boy and perform oral sex on him. The director then told Egan to do the same to him, but he says he resisted.

Singer denied these allegations, claiming they were 'outrageous, vicious, and completely false.'

Egan ultimately withdrew his lawsuit after turning down a $100,000 settlement from Singer with an option to re-file at any time.

There have also been a number of people who have come to Singer's defense, including his friend Robert Meyer Burnett.

Singer launched his career with The Usual Suspects and later earned raves for his work in the first two X Men films, though he followed that up with a number of underwhelming flops, including Superman Returns and Jack the Giant Slayer.

He previously went missing during the shooting of X Men: Apocalypse in 2015 and Superman in 2005.
