Rudy Giuliani has been ordered to prepare for trial after he failed to silence “sordid” sex claims hurled against him — and a lawyer made famous by a movie took up his accuser’s case.

The disgraced former New York City mayor and Donald Trump lawyer must sit for a deposition before the end of January next year — and be ready to go before a jury by the end of March, according to a judge’s order filed in New York Supreme Court this week.

It follows a 3-year fight by Noelle Dunphy, who claims she was subjected to booze-and-Viagra-fueled sexual harassment, including being forced to have sex, while working for Giuliani between 2019 and 2021. She claims to have recordings of many of Giuliani’s demands.

The order from Manhattan Judge Nicholas Moyne quashes efforts by Giuliani’s legal team to have the case thrown out — and brushes aside arguments that he’s too sick and poor to stand trial.
