The life of the 89-year-old actor ended this month and the cause of death is now clear. The 'Ed Wood' star died of a "hypovolemic shock" caused by a large loss of blood.

Other causes of death were abdominal bleeding, metabolic acidosis and vascular disease. Martin also suffered from hardened arteries. The day of death in a Los Angeles hospital was just a few weeks after Landau's 89th birthday. His press spokesman said earlier this month, according to the newspaper 'Mirror': "We are deeply sad to announce the death of legendary actor Martin Landau on July 15th, 2017 at 1:30 p.m. in the 'UCLA Medical Center' a short hospital stay he succumbed to unexpected complications.
