Odeon Star Semaphore Cinemas
cinema in Semaphore, Adelaide, South Australia, Australia

The Odeon Star Semaphore Cinemas, usually referred to as the Odeon Star, is an independent multiplex cinema in the beachside Adelaide suburb of Semaphore, South Australia. It is the oldest purpose-built cinema in Adelaide, opened on 22 May 1920 as the Wondergraph Picture Palace.
History
Picturedrome
In September 1910, before there were any indoor picture theatres in Semaphore, the Continental Wondergraph Company bought land on the esplanade, intending to establish a tea garden and open-air cinema. On Monday 26 December, Wondergraph gave the inaugural screening at its "Picturedrome", although the construction of the kiosk and tea garden had been delayed. The seating faced the sea, and several silent films were projected onto a solid concrete "silver wall", a new technology claimed to have been brought to Australia by the European company.
In winter, the Greater Wondergraph Company (formed in Adelaide in 1911) showed films at the Semaphore Town Hall, which was referred to as the Semaphore Wondergraph. In July 1912, a film of the British Antarctic Expedition led by Captain Scott was shown at the Semaphore Wondergraph. Competitor Ozone Theatres also used the town hall for showing films in the winter months.
A scheme to enclose the Picturedrome was advertised in November 1914, but this was apparently not concluded. Films were last advertised as being shown there at the end of summer in March 1915.
