BELLAIRE, Mich. (AP) — Filmmaker Michael Moore has filed for divorce after 21 years of marriage to Kathleen Glynn, his collaborator on the Oscar-winning “Bowling for Columbine” and other projects.

Moore filed a divorce complaint June 17 in Michigan’s Antrim County, where the couple has a lakefront home. It says their relationship has broken down and “there remains no reasonable likelihood that the marriage can be preserved.”

They did not immediately return phone calls seeking comment.
