In this 2008 AP file photo, actor Dennis Hopper, right, and his wife, Victoria Duffy, are shown after Hopper was awarded the "Commander in France's National Order Of Arts and Letters" in Paris.
The 73-year-old actor-director filed for divorce Thursday in Los Angeles, citing irreconcilable differences with Victoria Duffy, his wife of nearly 14 years.
Hopper has been battling prostate cancer and in October canceled all travel plans to focus on treatment.
Hopper is seeking joint custody of the couple's 6-year-old daughter and offering to pay spousal support to Duffy.
The Easy Rider star last year finished shooting the second season of Crash, a TV version of the Oscar-winning 2004 film that airs on the Starz network. Hopper also has several film projects in the works.
Phone and e-mail messages left for Hopper's manager, Sam Maydew, have not been returned.
