Mr. Baldwin declined requests to be interviewed for this article, and also declined an invitation to have people speak on his behalf. Several of his friends and colleagues also declined to comment this week.

Last fall dozens of women came forward to say that Mr. Toback, the filmmaker, had harassed or abused them. At that time Mr. Baldwin — who worked with Mr. Toback on films like “Seduced and Abandoned” — offered a circumspect defense of his friend, telling The Los Angeles Times that he “always heard Jimmy was peculiar” and adding, “I don’t know that Jimmy has done anything criminal.” Explaining why he had not yet condemned Mr. Toback, Mr. Baldwin said, “Well, I’m going to get around to that in my own way and in my own time.’’

He added, “I just hope people proceed with this very carefully.”

A few days later, Mr. Baldwin seemed to cast blame on Ms. McGowan, who said she was raped by the film mogul Harvey Weinstein. In a PBS interview, Mr. Baldwin said, “Rose McGowan took a payment of $100,000 and settled her case with him. And it was for Rose McGowan to prosecute that case.”

On Twitter, Mr. Baldwin has defended Dustin Hoffman from accusations of sexual misconduct, and gone after late-night TV hosts like Stephen Colbert and John Oliver, who he believes have persecuted men like Mr. Hoffman and Mr. Weinstein. Their shows “are beginning to resemble grand juries,” Mr. Baldwin wrote.

Last Sunday Mr. Baldwin took aim at Ms. Farrow, who has said that Mr. Allen, her adoptive father, molested her in 1992 when she was a child. (Mr. Allen has denied these claims and was not charged with any crime.) Mr. Baldwin said in a tweet that one of “the most of effective things Dylan Farrow has in her arsenal is the ‘persistence of emotion.’”
