NEXT ANSPACH-NICHOLSON CHAPTER: 11.

Byline: Marilyn Beck & Stacy Jenel Smith

Actress Susan Anspach has filed for Chapter 11 in Los Angeles bankruptcy court to prevent Jack Nicholson from selling her house while their legal war rumbles on.

The actress slapped a $1 million suit against her onetime love last year after Nicholson had paid some $400,000 toward the mortgage and taxes on her home and then moved to foreclose.

Anspach maintains the trouble started after she wrote a letter to Vanity Fair in 1994 complaining that an article on Nicholson had omitted the fact he had fathered a child with her during the shooting of ``Five Easy Pieces'' in 1969. As revenge, she claims, he has sought to oust her from the home she purchased in 1979. ``He has a vendetta against me,'' she said.

Nicholson's representative declined comment.

Anspach acknowledges that she signed a loan form when she went to him for help making the house payments when her career waned. But she insists, ``It was just a matter between family. He promised I could pay the money back whenever I could afford it. I was told that signing the loan was only a formality to help Jack with his taxes.''

In March, Nicholson's camp succeeded in getting three of the claims in Anspach's suit against him dropped. She now tells this column that on Monday his attorneys will be back in court ``pushing for a summary judgment against me - again trying to throw the case out of court.''

And where is the son in all of this? Caleb is now 25 and, says Anspach, very much on her side. Though Nicholson has avoided public recognition of Caleb, according to the actress, Jack and Caleb ``have become quite close in the last few years.''

Crying foul: Jane Seymour is upset over an article in the Washington Post accusing her ``Dr. Quinn, Medicine Woman'' company of overworking infant twins who were hired to alternate in the guest role of a 7-month-old. ``The story gave the impression we worked the babies all the way through, from morning until night, and it's just not true,'' she defends. ``Infants are not allowed to be before the cameras more than 4-1/2 hours a day. ... In this case, we had used one twin in the morning, and were using the other in the early evening. We had rented a hotel room for the family to use when the children weren't working. They also had the use of the (on-set) nursery. ... The family chose to remain on the set.''

The actress makes it clear, ``We pride ourselves on the way we look after babies. We would never overwork one - and the suggestion we would really hurt.''

As we reported Tuesday, the ``Dr. Quinn, Medicine Woman'' set is filled with babies - with Jane bringing her twins to work, producer Beth Sullivan also accompanied to work by her twins, and with infant triplets playing the role of Dr. Quinn's infant daughter.

The big-screen scene: Things simply won't seem to settle down for ``The Grass Harp,'' the much-belabored film adaptation of the Truman Capote work directed by Charles Matthau, and co-starring his father, Walter; Jack Lemmon; Sissy Spacek; and Piper Laurie. The film, made for a modest $10 million last year - amid some stormy discords between Fine Line Features and the younger Matthau - was supposed to have been released next month. But at this point the company is ``still evaluating'' when it should hit the market. October is being considered.

Laurie wants us to know, ``It's perhaps the best thing I ever made.'' She makes the point, ``There was a lot of pressure from the beginning. Tempers were tested a lot.'' She herself didn't start until ``Joan Plowright bowed out 10 days before shooting began - and I was called in to take her place.''

Four-part assignment: An Aug. 5 start date has been set for Mike Myers' ``Austin Powers: International Man of Mystery.'' That's the vehicle the ``Wayne's World'' star wrote for himself - about a swinging-'60s special agent defrosted after 30 years in cryogenic suspension - which New Line Cinema is hoping will yield a new, funny film franchise.
