Dermot Mulroney and Catherine Keener's marriage is no longer lovely or amazing.
Mulroney, 43, filed for divorce from Keener, 48, last Friday, citing irreconcilable differences. The couple have been separated since May 2005, according to court documents obtained by E! News.
In his Los Angeles Superior Court filing, Mulroney requested joint legal and physical custody of the twosome's seven-year-old son, Clyde Keener Mulroney. He also asked that property rights be determined by the court. [See the court documents here.]
The duo met on the set of Survival Quest in 1989 and tied the knot in 1990, meaning their union lasted a virtual eternity by Hollywood standards. They also shared the screen in 2001's Lovely & Amazing.
Mulroney can currently be seen on the big screen in the indie pic Gracie, starring Elisabeth Shue, and the dramedy Georgia Rule, starring Lindsay Lohan and Jane Fonda.
Up ahead, he stars in the drama Jolene, due for release later this year, and the heist film Six Bullets from Now, currently slated to begin filming in September.
Keener, who earned her second Academy Award nomination for 2005's Capote, will next be seen in the thriller An American Crime, based on the true story of an Indiana housewife who tortured and murdered a teenage girl in her basement in 1965. The film premiered at Sundance in January and will be released in select theaters in August.
Keener also stars in the upcoming big-screen adaptation of Jon Krakauer's Into the Wild, directed by Sean Penn, and in the kiddie film Where the Wild Things Are, based on Maurice Sendak's classic children's story by the same name.
