The lawyer representing Michael F. Egan III, who has accused "X-Men" director Bryan Singer of sexually abusing him when he was underage, told HuffPost Live on Friday that more recognizable Hollywood figures involved in sexually assaulting young men will be named next week.

"There's more Hollywood names. These are other men who Mike alleges were part of these pool parties in California and then also flew to the parties in Hawaii, where they sexually abused Mike. They're Hollywood insiders," said attorney Jeffrey Herman.

Herman told host Ricky Camilleri that he and his client have not yet named all parties involved because they need to take "certain procedural steps" before filing additional lawsuits in Hawaii. Herman expects the new names will be made public Monday, though he said under Hawaiian law he has until Thursday to file suit against the other "sexual predators."

AN 'ORGANIZED AND ONGOING OPEN SECRET'

Since Egan's lawsuit became public this week, Herman said he has been amazed by what he's discovered about the widespread nature of sex abuse in Hollywood and the unspoken knowledge of such conduct.

"I've seen a lot of things -- [defending victims of sexual abuse] is all that I do -- but I don't know that I've ever seen a more organized and ongoing open secret," he said. "I'm getting regular contacts from people saying, 'Oh, you should hear what's happening over here.'"

Herman added that he's been told about numerous "vile" rings of sexual predation, some of which overlap. But "the commonality of this is they're all men in Hollywood, all men using their positions of power and influence to sexually exploit children," he said.

'I'M NOT GOING TO BE BULLIED'

Singer's attorney has shot back against Egan, Herman and their allegations, declaring on Friday that receipts, telephone records and production schedules can prove Singer was not in Hawaii at the time Egan claims he was assaulted. Singer's lawyer also vowed to file a countersuit for "malicious prosecution."

Herman said he plans to move forward with Egan's suit no matter what Singer's representatives say.

"I'm not going to be bullied, I'm not going to be intimidated by someone threatening to do something to me because I'm representing a victim," he said. "I am the voice of these victims who have been silenced."
