Los Angeles , California ( CNN ) -- If Dennis Hopper attends the dedication of his star on Hollywood 's Walk of Fame Friday , it may be the last time his fans see the actor alive . Hopper is dying of prostate cancer , according to documents filed in his divorce case this week . Hopper 's acting career has spanned almost six decades . In the '50s he had roles in several TV shows and films , including `` Rebel Without a Cause '' ( 1955 ) and `` Giant '' ( 1956 ) . He became a Hollywood sensation for `` Easy Rider , '' the 1969 film he directed and co-wrote in which he played a dissolute , countercultural biker . He was twice nominated for Oscars . Hopper , 73 , is undergoing radical chemotherapy for advanced , metastasized prostate cancer , his doctor said . He is too weak and ill to be questioned by lawyers in the divorce , but attending Friday 's ceremony `` is a positive experience in every way , '' his doctor 's sworn statement said . Hopper 's lawyer has not confirmed if the actor will attend the ceremony in front of the Egyptian Theater on Hollywood Boulevard , but his doctor is recommending it . `` I believe the ceremony honoring his career may be something which he will actually enjoy in the company of his daughter , who he hopes will attend with him , '' Dr. David Argus said . Dennis and Victoria Hopper married 14 years ago and they have a 6-year-old daughter , Galen . They separated in January when he filed for divorce , claiming the stress of their relationship was threatening his life as he battled cancer . `` The presence of his estranged wife is hampering Mr. Hopper 's present cancer care as she introduces significant additional stress into his life , '' Argus said . `` The less Mr. Hopper has to do with his estranged wife at this time , the more likely he is to have his life extended . '' Hopper 's lawyer , Joseph Mannis , argued that Victoria Hopper , knowing he was `` extremely ill and fragile , repeatedly engaged in conduct which appears to have been calculated to subject [ Hopper ] to severe emotional distress . '' This distress `` subjected [ Hopper ] to a significant risk of causing his premature death , '' Mannis wrote . The divorce case is set for an April 5 hearing in Los Angeles County Superior Court , but lawyers for Victoria Hopper are trying to force Dennis Hopper to take part in a deposition . His lawyer and doctor told the judge it could kill him . `` Compelling Mr. Hopper to participate in a deposition where he is being asked questions he is compelled to respond to under oath regarding his wife and/or his daughter could actually threaten his ability to survive his current health crisis , '' Argus wrote . Hopper , who weighs `` a little over 100 pounds , '' is `` extremely weak and extremely ill , and he tires very quickly , '' he said . Emily Davis , Hopper 's personal assistant , said in a sworn statement that Hopper is `` only able to have brief conversations at times when his nurses permit him to have such conversations and then only for very short periods of time . '' `` He is not able to concentrate and he tires quickly , '' Davis said . The court filing also contends that Hopper 's finances have dwindled with his illness . An affidavit from his accountant said the cost of his cancer treatments exceed his income , which is $ 58,000 in annual residual payments from his TV and movie roles . His last acting job was last year when he completed the television series `` Crash . ''
