SACRAMENTO, Oct. 17 – U.S. District Court Judge Thomas J. MacBride has banned the Northern California showing of a film depicting the exploits of mass slayer Charles Manson and his cult until a jury is sequestered or returns a verdict in the trial of Lynette Fromme.

MacBride issued the order after he viewed the 90-minute film in a closed-door court session in a grand jury hearing room yesterday afternoon.

The order was sought on behalf of Miss Fromme, accused of trying to murder President Ford in Sacramento last September 5.

The wispy 26-year-old defendant, described as the “most slavish” of Manson’s cult of followers, later protested loudly in court to another Manson follower, Sandra Good, that the film showed “a lot of dirty blood and sex.”

After a U.S. marshal warned her to be quiet or she would be removed from the courtroom, Miss Fromme sat quietly for a time and then stood, indicating to a matron that she wished to leave the room.

As she was escorted out, she said loudly, “the problem is they put the whole thing on Manson. They made us look like innocent children.”

Miss Fromme was returned a few minutes later when Mac Bride entered the courtroom to make his ruling.

MacBride, who several times previously has warned Miss Fromme about making potentially damaging utterances in the court, warned her again, saying there is nothing he could do about the outburst, but adding:

“If you make some bonehead statement, that’s your problem.”

The film, entitled “Manson”, was started in 1969 before the Tate-LaBianca murders for which Manson and other members of his cult were convicted.

A portion of it shows Miss Fromme fondling a rifle and saying, “you have to make love with it. You have to know every part of it and know you can pick it up any second and shoot.”

Federal Defender E. Richard Walker moved to have the film banned before he was relieved as Miss Fromme’s co-counsel in the case.

He asked that it not be shown in a 25-county area from which the Sacramento federal court selects potential jurors. He said showing the film would prejudice Miss Fromme’s right to a fair and impartial jury, “free from outside influences.”
