moore-glynn-ec434c87ffbfec99Filmmaker Michael Moore, 59, has filed for divorce after 21 years of marriage to Kathleen Glynn, 55, his partner on the Oscar-winning “Bowling for Columbine”.

Glynn is listed as producer or executive producer on most of his projects going back to 1994′s “TV Nation.” She has worked on most of Moore’s hard-hitting documentary films, including “Fahrenheit 9/11,” “Sicko” and “Capitalism: A Love Story.”

According to a complaint filed on June 17th in a circuit court near their home on Torch Lake, the power couple is going their separate way because their relationship has broken down.

The Antrim County Circuit Court complaint says Moore and Glynn no longer live together and that there is “no reasonable likelihood that the marriage can be preserved.”

They were together for nearly a decade before their 1991 marriage, having met on the staff of the alt-weekly newspaper in their hometown of Flint, Michigan, in the early ’80s. They own a home in the Traverse City area and have no children.

Glynn has yet to answer the divorce complaint and has no attorney of record, according to Antrim County records.

While Glynn pursued some of her own projects, she was best known for her work with her husband, but told the Flint Journal in 2006 she didn’t mind standing in his shadow: “At a certain point, you buy a car from a salesman, and you don’t think about the 200 people who made the car.”

The divorce is likely to involve millions of dollars, including the couple’s Torch Lake home, which has a taxable value of $1.2 million, according to Antrim County property records.

Moore’s complaint for divorce seeks a temporary order and judgment dissolving the marriage and restraining both parties from selling or transferring the couple’s assets to others, including stocks, bonds, limited liability companies, real estate, household furniture and works of fine art.

A final hearing is scheduled for Sept. 10.
