Dennis Hopper: My Wife is Killing Me

Dennis Hopper has filed legal papers in his bitter divorce case ... Dennis says he's perfectly capable of making decisions, and his doctor claims the less Dennis has to do with his estranged wife, Victoria, the longer he will live.

In the documents, Dennis' lawyer, Joe Mannis, says while his client battles advanced prostate cancer, Victoria has "repeatedly subjected [him] to severe emotional distress."

According to Dr. David Agus' declaration, "The presence of his estranged wife is hampering Mr. Hopper's present cancer care..." Dr. Agus added, "It is my belief and recommendation that the less Mr. Hopper has to do with his estranged wife at this time, the more likely he is to have his life extended."

Dennis is asking the judge for an order keeping Victoria 15 yards away from him and barring her from his residence.

Dennis filed for divorce against Victoria last month. She claims Dennis' adult children are pulling his strings and want to cut her out of his will. In their declarations, Dennis and his doctor say the actor is of sound mind to make his own decisions.

Under the prenup between Dennis and Victoria, if they divorce she loses her 25% cut of Dennis' estate.

In Dennis' declaration, he says Victoria's mother "...told me in November of 2009 that I should simply leave the bulk of my property to [Victoria] as I was going to die soon. I found this statement distressing, inappropriate, bizarre, and disturbing."

Dennis also says last December, Victoria and her mother woke him up in the middle of the night and grilled him about how much money and property Victoria would get when Dennis died.

As for Victoria's claims that Dennis smoked medical marijuana in front of their young girl, he says he has never smoked in front of the child. Dennis says Victoria's demand that he not smoke within six hours of seeing their daughter is "an absurd request." He says he would agree to not smoke pot within one hour of visitation.

Dennis is asking for daily visitation rights to 6-year-old Galen between 5 and 7 PM.

We're told the prenup says Victoria must leave Dennis' compound where she currently resides, 60 days after divorce papers were filed -- so the move-out date would be March 11.

And Dennis wants Victoria to give him his stuff back, mainly artwork.
