CHANCES are you have seen The Guns of Navarone (Pearl 9.30pm. Original Running Time 159 mins) more times than you care to remember, and due to the distinct lack of anything better to view tonight, you may just have to again. But hey, it's a good film anyway isn't it? Yes it is, if you are into lots of violence, guns and death. This is certainly not a film for those looking for a laugh or a bit of intellectual stimulation, but the plot is not a bad one. Based during World War II, a commando unit is set up to destroy the German Army's colossal guns that are built into a strategic Turkish island guarding a channel to the Aegean Sea. The all-star cast, which includes Gregory Peck, David Niven and Anthony Quinn, is impressive but performances range from dismal to mediocre, but with so little choice tonight, it is still worth watching. YET another Steven Spielberg production is on offer tonight in the form of Always (World, 9.30pm. ORT 121 mins). Not one of his better offerings, this film about a fire fighter who dies and returns as a ghost to help his wife re-marry, drags on like a midday soap for more than two hours. The good cast consisting of Richard Dreyfuss, Holly Hunter and John Goodman seem to strain in bringing out any emotion from the lifeless plot and laughs don't come easily. Don't be surprised if you are reaching for the remote control 20 minutes into the film as the cameo appearance from Audrey Hepburn does little to ease the yawns. SALLY Round and the team from Inside Story (World, 8.30pm) will be serving up their weekly feast of current affairs. This week, Karen Haynes is sent to Nepal to look at the problems Gurkhas face upon their return home, their elite jobs and recruitment in the Himalayan country. Vivian McGrath talks to the families of victims of the Australian serial ''backpacker'' killer. She also has a chat to the police detectives who are handling the case on the methods they are employing to solve the mystery and find the culprit. Janine Graham, meanwhile, takes a look at Hong Kong's new heritage trail - a tourist attraction that takes visitors back into Tang Dynasty China with period costumes and pagodas that almost seem like the real thing. ROLL up, roll up. Barnum Circus is currently in town and Star Plus will be running the biographical film of its creator, Barnum (8.30pm. ORT 104 mins). Phineas Taylor Barnum was the brains behind the merging of ''show'' and ''business'' that created one of the most entertaining and successful spectacles to tour the world and this amusing and intriguing feature-length look at his life entertains as much as the live show. Burt Lancaster puts in a surprisingly lively role as the outrageous, imaginative promoter, only to be tarnished with the mediocre supporting cast of Hanna Schygulla and Sandor Raski. ON the current affairs front, The Pearl Report (Pearl, 7.20pm) will be talking to BBC correspondent Simon Long, Dr Miron Mushkat of Lehman Brothers and Kan Fook-yee, on the significance of China's shadow government for Hong Kong. Presenter Lulu Yu will referee the panel of experts as they debate and discuss the pitfalls of the breakdown in Sino-British talks.
