Michael F. Egan, the 31-year old plaintiff who sued Bryan Singer last week for sexual abuse for events that occurred when he was 15, came forward again Monday to file similar charges against three additional men: former president of BBC Worldwide America Garth Ancier, former president of Disney TV David Neuman, and Gary Goddard, a designer who created theme park attractions for Universal Studios.

None of the new defendants have yet responded to the suit.

Egan's lawyer Jeff Herman presented the claims Monday during a press conference held in Beverly Hills. He was seated alongside Egan and Egan's mother, Bonnie Mound, who thanked the press for attending the event and defended her actions as a parent, sometimes becoming emotional during the proceedings.

"Fourteen years ago, no one would have been here," she said. "I wrote every news organization, from Oprah to 20/20… I wrote hundred of letters to attorneys. No one wanted to do anything."

Last week, Singer's lawyer Marty Singer called the initial suit, filed a bit over a month ahead of the director's latest project, X-Men: Days of Future Past, "absurd and defamatory" and has threatened to countersue Egan and Herman for defamation. The director bowed out of this past weekend's WonderCon convention held in Anaheim. (Producer/writer Simon Kinberg attended in his stead to show off clips from the upcoming X-Men movie.)

Singer also canceled an upcoming MPAA symposium he was scheduled to attend in Washington, D.C., with Vice President Joe Biden early next month. And his name has been removed from television promos advertising the new ABC show Black Box, which Singer executive produced.

Whether other charges will be filed remains to be seen. Attorney Herman called the incidents part of a "Hollywood sex ring" and both he and Egan encouraged other victims to come forward.

Said one Hollywood insider of the case: "It's not going to go away. This is a perfect storm of bad behavior, a movie coming out and a real, live person who is willing to put his face to it. This has the makings of something bigger."
