This is the Italian actress Pier Angeli 1932 – 1971
Mostly forgotten now but she was a gloriously believable actress as the clip below from the 1960 British film The Angry Silence clearly demonstrates.
At the relatively young age of 39, she was found dead at her home in Beverly Hills from a drug overdose.
Watch her closely during these scenes from The Angry Silence...
