LOS ANGELES -- Dennis Hopper is terminally ill and too weak to be questioned by his wife's divorce attorney, according to court documents.

Hopper's attorney, Joseph Mannis, filed a declaration in Los Angeles Superior Court Wednesday outlining the actor's declining health as he battles prostate cancer.

According to Mannis, the 'Easy Rider' actor is too weak to participate in a deposition in his divorce case.

His physician, Dr. David Agus, wrote in the court filing that Hopper weighs less than 100 pounds and is unable to carry on long conversations.

Agus states that undergoing a deposition "could actually threaten his ability to survive his current health crisis."

However, the doctor says he has approved an appearance by Hopper as he receives a star on the Hollywood Walk of Fame because it is likely to be a positive experience.

The grim prognosis contradicts previous filings in the divorce proceedings that were bullish about Hopper's recovery chances.

Hopper, 73, and his wife, Victoria, have been locked in a bitter feud since the actor, director and artist filed to end the couple's nearly 14-year marriage in January.

A phone message seeking comment from Victoria Hopper's attorney, Sorrell Trope, was not immediately returned.

Mannis did not return a call seeking further comment.

Hopper filed a declaration last month saying he was undergoing promising chemotherapy treatments and remained hopeful "that this treatment will be successful so that I may soon resume the full enjoyment of my life and work."

Dennis and Victoria Hopper have agreed to stay 10 feet away from each other while the divorce is ongoing. She has stated in court filings that Hopper filed for divorce to cut her out of her inheritance, a claim the actor has denied.

The case is scheduled for a court hearing on April 5.
