Apart, they might have seemed sisters. Together, the resemblance was less pronounced.

They were, as a matter of fact, "very good friends" and "yes," said Bibi Anderson, "in a way" it had been she who first introduced Liv Ullman to Swedish film director Ingmar Bergman.

"We had been friends for several years, and then Bergman did 'Persona' with us both. And we're still friend," said Anderson at the party Sunday night given for her and Ullmann by Swedish Ambassador and Countess Wachtmeister.

What brought the two actresses together in Washington was the TV series which they did for Bergman in 1973, "Scenes From A Marriage," now being shown in six weekly installments on Channel 26. WETA-TV executives were out in force, of course, as were executives from PBS, CPB and WNET ("the alphabet soup gang," explained one) from New York.

Ullmann, who's appearing at the National in the Eugene O'Neill play "Anna Christie," said she had seen the TV series in Sweden but not here.

"Well, remember the part where you go to the bathroom? That was a big issue for us, believe me," said George Page, director of WNET's program development and broadcasting, introducing her to PBS President Larry Grossman. "He said 'let's see it'"

Ullmann stood almost transfixed, a faint blush rising gradually up her throat to her cheeks.

"It's not me," she said. "At a party, I would go home rather than ask for the lady's room."

The little knot of listeners standing around her looked stricken.

"No, no," Ullmann insisted."I don't go to the bathroom (in the film). It was out in."

Ullmann, when sufficiently recovered, turned her attention to her daughter Linn, age 10, who like Bibi Anderson's daughter, Jenny, 6, had accompanied her mother to the party.

A number of the guests had brought, copies of Ullmann's new book, "Changing" for her to sign. She said she had been somewhat disappointed at some critics concern over it autobiographical aspects when what she wanted to tell was "a common story," something she could share with other women about her life. She never does say in her book why she never married Linn's father, Ingmar Bergman. And Sunday night she didn't say either.

She said she had recently completed a film with David Carradine directed by Bergman and that while he is living in Munich at the moment "he loves Sweden and I am sure he will go back someday." He had not been "upset about the govenment but instead over some people in the tax department who judged him unfairly," she said.

Anderson is rehearing in New York for the late April opening at the Kennedy Center of Arthur Miller's new play, "The archbishop's Ceiling." She only needed to read the first act, she said, to be convinced that it was a part she wanted to play. She called Miller "one of the greatest playwrights" alive today.

The guest list had been drawn up jointly by the Swedish Embassy and WETA.It included some administration types with solid Scandinavian backgrounds like Agriculture Secretary Bob Bergland, and from the Senate, Wisvonsin's Gaylord Nelson. John Lindsay, now of "A.M. America," but once mayor of New York City, turned up with media companions, and others in the throngs included Rowland Evans, George Stevens Jr., Tom Fischandler, and Chief of Protocol Evan Dobelle.
