The Siege Of Pinchgut (1959) (UK-import)
Ealing Studios' final film is a fast-paced action thriller set in Sydney, Australia. Aldo Ray stars as Matt Kirk, a wrongly-convicted prisoner who, along with three other inmates, escapes from jail aboard a small boat. When the fugitives run aground on Pinchgut Island, a small military fortress in the middle of Sydney Harbour, a desperate siege begins during which the keeper and his family are held hostage and a loaded cannon is trained on the city's waterfont.
