The So Have I Movement takes time. Even today, Sexism is well entrenched and there's a lot of pushback. So even after Polanski gets convicted, there's going to be pushback and anger from the sexist manbabies.
I mean even Brock Turner has idiots trying to play down what he did and somehow blame the victim.
Speaking of this movement, I actually had some thoughts on The Roman Polanski Movie: It's based on @PRM's Suggestion with some of my own modifications and ideas.
The beginning shows Samatha Geimer in the aftermath of her assault. She returns home and tells her mother.
The police go and arrest Polanski (despite him trying to get them to shrug off the accusation) from there we see him get processed, fingerprinted, etc.
The District Attorney, John Van de Kamp assigns the case to two prosecutors and imagine a man and a woman. The man is a little skeptical of the case (Partially because he knows how these things go, but there is a part of him that's skeptical) whereas the woman is more willing to take it on.
They meet with Geimer, her parents and her attorney where she tells them the whole story. The man is still a little skeptical but he's not a dick about it and the woman fully supports her.
They have an arraignment for Polanski where the charges are laid out in full terms. He pleads not guilty. Later on, his attorneys and himself meet with the prosecutors and the District Attorney where they offer a deal. Polanski will plead down to lesser charges, "Unlawful Sexual Intercourse with a Minor". When Polanski and his lawyers leave, they discuss it.
Both de Kamp and the man agree they should consider it. The woman is hesitant and says they should talk this over with Geimer and her parents, as well as her attorney.
As you can imagine, Geimer, her parents, and her attorneys are not happy when they are told. This is what I would consider one of the most important scenes in the movie because Geimer says she will not stay silent, she will speak up. Apart of that is I imagine that Geimer looks straight at the man Prosecutor and asks him point blank "Do you believe me?" He's somewhat caught offguard by the question and takes a moment to answer "Yes". Geimer says she wants to go public which makes the prosecutors and her attorney nervous, knowing what usually happens to someone (particularly woman) who accuse a high profile and powerful figure that something awful of this magnitude. She says "I know the risks, but I don't care."
Samantha does her interview with the LA Times. There's a monologue of people getting their papers and seeing the interview. Especially Jack Nicholson and Anjelica Houston who are at this point are like "We're screwed." Marilyn Monroe and Shirley Temple Black are also seen reading the interview; Monroe shows particular horror. However, there are a lot of celebrities and journalists who defend Polanski; many outright slut shame her, others express doubt, and they all play up Polanski's accomplishments as a director. Some of Polanski's lawyers appear on TV outright smearing Geimer. The toll of all of this is shown coming down on Samantha and her parents. Especially her mother who is just you have to imagine full of guilt for introducing her daughter to Polanski in the first place.
However, then Polanski gives the infamous interview where he pretty much says, "Everyone wants to fuck little girls." He also plays down what he did. This is a major turning point in the case; the male and female prosecutors meet Van Der Kamp in his office. He shows them the interview and they are all appalled by it. "Who does this man think he is?" de Kamp asks. Neither the Man or the Woman know what to say (as a sign of development the man is shown to be visibly disgusted, showing that he's more willing to believe her now). Van der Kamp pretty much tells them "Whatever you need to do, you make sure this guy goes to prison.
Marilyn Monroe meets the Geimer Family at their house and has a talk; we find out that they're strongly considering dropping the charges, but Marilyn encourages them to keep fighting, relating her own experiences and offering to pay for their legal fees. She then gives her own public statement in support of Geimer in an interview, before publishing an Op-Ed in the LA Times relating her experience. We also see Shirley Temple Black publish her Op-Ed, as well as her autobiography (this could be around August or September, 1977). We see some of Polanski's Apologists trying to play it down, but it's clear that a few of them have been affected even if they're in denial.
The Trial begins. Samantha Geimer goes first, and we finally see the scene (it's pretty horrific). She maintains her composure under the cross examination, but breaks down afterwards. Nicholson and Houston are put on the stand, and not only are they forced to admit that they left Geimer alone, Huston is forced to admit that she came back and tried to get Polanski to open the door but gave up when he didn't.
Polanski takes the stand, and is aggrieved and indignant. While they are able to trip him up in a few places (they bring up the interview, and he's unable to explain why he didn't unlock the door when Angelica Houston knocked on it) he maintains his composure and acts like he's being persecuted.
I'm also thinking that there's a scene where a brick is thrown through the Geimer's house, with the word "whore" written on the brick.
The Closing Arguments came. The women gives the closing argument, being firm but compassionate. Three days pass, and the jury returns with a verdict. Polanski is smug at first, but as the first guilty charge is read out his smile vanishes, and he becomes increasingly shocked as he's found guilty of the other charges and the sentence is declared. As Polanski is led away, Geimer looks at him without fear.
The scene outside the courthouse is triumphant, and Polanski's lawyers can only rant about how they intend to appeal.
Note: I'm thinking the movie can come out in 1997 or so ITTL and it does cause controversy. Some of the celebrities who took Polanski's side are put in the hot seat all over again. Scorsese in particular is dogged.
