The attorney for the man accusing "X-Men" director Bryan Singer of sexual abuse has filed additional, similar cases against three Hollywood executives.

Garth Ancier, David Neuman and Gary Goddard were named in three separate complaints, filed by attorney Jeff Herman in Hawaii, accusing them of sexually abusing Michael F. Egan III. Last week, Singer was accused in a federal lawsuit of drugging and sexually assaulting Egan in the 1990s.

Ancier is a prominent television executive who has held senior positions at Fox and NBC. Neuman is a former senior Walt Disney television executive. Goddard is the founder of a firm that designs theme park attractions, hotels and resorts and produces live shows.

They could not immediately be reached for comment.

An attorney for Singer has called the lawsuit against his client "absurd and defamatory."

The lawsuit against Singer filed on behalf of Egan claims that Egan was forced into a "sordid sex ring" in the entertainment industry in which underage boys were supplied alcohol and drugs. Egan alleges that the assaults took place at parties in California and Hawaii when he was 17.

The lawsuit also says Singer promised Egan jobs in film, commercials and other projects. The plaintiff is now 31 and lives in Nevada.

The claims made "about Bryan Singer are completely fabricated," Marty Singer, a lawyer for the director, said in an email last week. "We look forward to our bringing a claim for malicious prosecution against Mr. Egan and his attorney after we prevail."

Singer's next big-budget movie, "X-Men: Days of Future Past," is to hit theaters May 23. Singer broke onto the Hollywood scene with the 1995 thriller "The Usual Suspects."

Herman was also the attorney behind the 2012 lawsuit filed against former Elmo puppeteer Kevin Clash.
