LATEST: Attorney says failing Dennis Hopper weighs 100 lbs. from his prostate cancer as he demands estranged wife Victoria Duffy return stolen art.

In a  legal doc filed in LA County Superior Court the Easy Rider star claimed that Duffy "surreptitiously removed from my home very valuable personal property while I was extremely ill, refused to tell me where the property was when I asked her, and then left town."

The missing art including a portrait of the icon by Andy Warhol and sculptures are said to be worth more than $1.5 million.

On Friday Hopper will emerge from seclusion o get his long over due star on the Hollywood walk of fame with pal Viggo Mortensen.

Wife Duffy won’t be attending– she has to honor a court mandated restraining order to stay away from the cancerous star.

Sadly, Hopper appears to be losing his battle with cancer — according to new legal docs Hopper weighs a little over 100 pounds and may not survive long enough to make a full deposition in his divorce battle.
