A prosecutor said on Friday that the Hollywood producer Harvey Weinstein was “an abusive rapist” and “a predator” who used his power to manipulate and assault several women in the movie business, then stayed in touch with them to ensure their silence and compliance.

“He had a surefire insurance policy: That the witnesses were standing in line to get into his universe,” Joan Illuzzi, an assistant district attorney, told the jury during her closing arguments at Mr. Weinstein’s rape trial.

“The universe is run by me,” she added, adopting Mr. Weinstein’s point of view, “therefore they don’t get to complain when they’re stepped on, spit on, demoralized and yes, raped and abused by the defendant.”

Ms. Illuzzi’s summation of Mr. Weinstein’s tactic — “trick and surprise,” she called it — was a dramatic finale to the trial in State Supreme Court in Manhattan, which has emerged as a watershed moment for the #MeToo movement.
