Bryan Singer has been accused of sexually abusing a 15-year-old boy.

The 'X-Men: Days of Future Past' director has been named in a lawsuit which was filed in Hawaii yesterday (16.04.14) which claims he first preyed on Michael F. Egan, now 31, at a Californian house party in the late 1990s, where under-age youngsters were allegedly plied with drugs and alcohol and ''taken advantage of''.

The suit claims: ''Defendant Singer told plaintiff how 'this group' controls Hollywood. Singer masturbated plaintiff and then performed oral sex upon him. Defendant Singer solicited plaintiff to perform oral sex upon him, which plaintiff resisted...

''Singer flagrantly disregarded plaintiff's unwillingness to submit, and forced plaintiff's head underwater to make plaintiff perform oral sex upon him. When plaintiff pulled his head out of the water in order to breathe, defendant Singer demanded that he continue which plaintiff refused.

''Defendant Singer then forced plaintiff to continue performing oral sex upon him outside of the pool, and subsequently forcibly sodomised plaintiff.''

Jeff Herman, the accuser's attorney, told the New York Daily News newspaper: ''The stories that I've heard of what went on at the estate are truly despicable.''

The attorney for the alleged victim - who is heterosexual - claims the filmmaker promised his client, an aspiring actor, a role in a movie and they had ''numerous'' sexual encounters when he was 15 and 16, and they took multiple trips to Hawaii when he was 17.

Marty Singer, a lawyer for the director, claimed the suit - which sees Egan seek damages in excess of $75,000 for ''catastrophic psychological and emotional injuries'' - is an ''obvious attempt to get publicity.''

He added in a statement: ''The claims made against Bryan Singer are completely without merit. We are very confident that Bryan will be vindicated in this absurd and defamatory lawsuit.''
