Five women are suing actor #BillCosby for acts of sexual abuse — including an alleged incident in his “The Cosby Show” dressing room — which happened as they attempted to break into show business several decades ago.

The alleged victims said Cosby, 85, had posed as a mentor to them — but he instead drugged them, groped them, raped them and sexually abused them as far back as 1969, according to a lawsuit they filed Monday evening in Manhattan Supreme Court.

The plaintiffs are also suing three companies — NBC Universal Media, Kaufman Astoria Studios and the Carsey-Werner Company — for their apparent failures to intervene and protect the women.
