It is also interesting to look (further down the same page) at the 'retrospective awards' (with benefit of hindsight) for 1953. It was a good year: Farenheit 451, Childhood's End, More than Human (that would be my choice), A Case of Conscience, the Nine Billion Names of God (the latter downloadable). And in 'Long Drama': 'The Thing from Outer Space' though I perfer John carpenter's 1982 version.
