In the papers, which state that Hopper weighs about 7st 2lb (45kg), he is described by his doctor, David Agus, as extremely weak and unable to have long conversations.
Joseph Mannis said his client was therefore unable to be questioned by lawyers of his wife of 14 years as part of divorce proceedings.
She has also claimed that he filed for divorce so that he could cut her out of her inheritance.
Last month, a judge ruled that Mrs Hopper must stay at least 10ft (3m) away from her husband after the actor said he wanted to eliminate unnecessary stress. How ridiculous, typical of the US.
