One of the best science-fiction movies you’ll see, District 9 (Sunday, 10.55pm, Action), from The Lord of the Rings producer Peter Jackson and director Neill Blomkamp, is not only highly original, it packs in a lot of social relevance. Aliens, sick and malnourished and quickly nicknamed “prawns”, land on earth, only to be sequestered in a slum on the fringes of Johannesburg. Brilliant noirish mystery Gone Baby Gone (Tuesday, 8.30pm, Thriller), directed stylishly by Ben Affleck and starring his brother Casey, is based on the novel of the same title by great Boston crime writer Dennis Lehane of Mystic River fame. A little less stylish but highly entertaining is The Man From Hong Kong (Tuesday, 9.30pm, World Movies), the latest in a season of Aussie Exploitation movies. The 1975 action film, directed by the underrated Brian Trenchard-Smith, was the first Australian-Hong Kong production shot in both nations and starred Shanghai-born Jimmy Wang Yu and former 007 George Lazenby. Legendry Aussie actors Bill Hunter and Frank Thring also appear and director of photography was the modest local boy , who went on to grab an Oscar for Peter Weir’s Master & Commander.
