We finally know what killed actor Rip Torn. It was Alzheimer's, according to a death certificate obtained by TMZ. The 88-year-old died at his Connecticut home in July, but no cause of death was given at the time. The certificate lists the death as due to or related to the disease with which he was diagnosed years earlier, per TMZ. It adds the actor, whose career spanned seven decades, was laid to rest in Poughkeepsie, New York. As Film-News notes, he was probably best known as Agent Zed from the Men in Black films and as Artie on the Larry Sanders Show. (More Rip Torn stories.)
