Gene Maddaus Senior Media WriterScott Rudin has had a public reputation as an abusive boss for decades. But this week, for the first time, he began to experience some consequences for it.A24 let it be known that it was cutting ties with the producer, who had delivered such films as “Lady Bird” and “Uncut Gems.” Rudin was compelled to “step back” from his Broadway work, and when that didn’t stop the drumbeat, he dropped out of his film and streaming projects as well.The accountability remains tentative, as the vast majority of stars and directors who have worked with him over the years have stayed silent.
