One of the most popular and influential shows in the history of television for many viewers the original Star Trek (1966-9) defines good science fiction: however much it tries to be about the future, it cannot help but reflect the values of its own time, and Star Trek's vision was very much a product of creator Gene Roddenberry's 1960s liberal-humanist idealism. Conceived at the height of the Cold War and during the escalation of the Vietnam conflict, his was a radical vision of a world where national and racial differences have been put aside and all people work together. With a policy of non-intervention in the affairs of other civilisations and violence only as a last resort, Star Trek embodied a lost dream, a fantasy of what America could have been had John F Kennedy not been assassinated in 1963. Captain James Tiberius Kirk (William Shatner) had the middle name of a Roman emperor but otherwise shared his initials with the late president, and both were young, good looking, womanising, charismatic popular heroes. If Kirk didn't uphold truth, justice and the American way from the White House, a big white starship was the next best thing. There was even a Russian, Mr Chekov (Walter Koenig), on the bridge and the show delivered network TV's first inter-racial kiss between Kirk and Uhura (Nichelle Nichols). Even though there was a white American male in control, it was still all a bit much for 1960s' mainstream TV, hence the voyages of the Starship Enterprise, boldly going on its five-year mission to explore strange new worlds, only lasted three seasons and 72 episodes before being cancelled in 1969, the year Man first walked on the moon. While the once-groundbreaking special effects now look routine, and the then-radical politics have now become part of the Politically Correct global mainstream, Star Trek retains an enduring popularity due to its strong storytelling-the show employed such top science fiction writers as Robert Bloch, Harlan Elllison, Richard Matheson, Norman Spinrad and Theodore Sturgeon-and admirable characters. Spock (Leonard Nimoy), McCoy (DeForest Kelley) and Scotty (James Doohan), Sulu (George Takei), Kirk, Chekov and Uhura remain icons for a world short of real heroes: loyal to the end, honest and utterly dedicated, these were the friends and colleagues who week after week trusted each other with their lives. Devoid of cynicism and self-interest the crew of the USS Enterprise never let anyone down and ultimately that is a very big reason for Star Trek's enduring popularity. [+]

From the outset, Star Trek: Deep Space Nine was about conflict. Producers Rick Berman and Michael Piller challenged the utopian ideals of Gene Roddenberry's Star Trek universe to create something totally different from its predecessors. This meant no familial camaraderie, squeaky-clean Federation diplomacy or beige décor. Instead they wanted interpersonal friction, ruthless enemies (Gamma Quadrant Imperialists-The Dominion) and rebellion at every turn. The DS9 concept was originally facilitated by introducing the Cardassian/Bajoran war during The Next Generation's final days. After a muted first reception fans gradually came to accept the new look, but no one liked Star Trek without a starship and eventually the producers capitulated to viewers' wishes by introducing the USS Defiant (an apt name) in Season 3. Relying far less on technobabble than TNG, DS9 was unafraid to focus on matters of the spirit demonstrating a gutsy independence from its parent shows. Taking up the gauntlet thrown down by Babylon 5, improved CGI space battles also became a fan favourite. Throughout the increasingly serialised story arc there were rebellious factions within the different establishments: Kira had belonged to the Shakaar resistance cell; The Maquis was Starfleet vs. Cardassians; Section 31 was a secret Starfleet group; The True Way was a Bajoran group opposed to peace; the Cardassians had their Obsidian Order and the Romulans their Gestapo-like Tal Shiar.

After creating many of the innovative special effects for 2001: A Space Odyssey, Douglas Trumbull tried his hand at directing, and 1971's Silent Running marked an impressive debut. (In addition to creating the visual effects for Close Encounters of the Third Kind and directing 1983's Brainstorm, Trumbull later turned to the creation of high-tech cinematic amusement park rides. ) One of the best science-fiction films of the 1970s, Silent Running stars Bruce Dern as Freeman Lowell, a nature-loving crewmember aboard the Valley Forge, a gigantic spaceship in a small fleet that carries the last surviving forests of the Earth, which has fallen victim to overpopulation and ecological neglect. Freeman's name reflects his nonconformist philosophy, which runs counter to the prevailing recklessness of his three ill-fated crewmates, who are eager to jettison their precious payload and return to the bleakness of Earth. Before they can sabotage the forests, Freeman does what he must, and spends the remainder of his mission with three robotic "drones" as his only companions, struggling to maintain his sanity in the vastness of space. Dern is superb in this memorable role, representing the lost soul of humankind as well as the back-to-nature youth movement of the 1960s and the pre-Watergate era. (Appropriately, Joan Baez sings the film's theme song. ) A rare science-fiction film that combines bold adventure with passionate social conscience, Silent Running will remain relevant as long as the Earth is threatened by the ravages of human carelessness. -Jeff Shannon, Amazon. com.

UniSol Luc Deveraux is back in Universal Soldier-The Return. Jean-Claude Van Damme gallantly attempts to resurrect interest in his tepid career with this action-riddled roller-coaster ride. Set in the not-too-distant future, here Deveraux has been employed by the government to oversee the new UniSol project. What is UniSol? It's a military plan to turn dead soldiers into invincible fighting machines (see the first Universal Soldier for more details). It's also the scheme that went horribly wrong when the soldiers turned psycho, killing the scientists who created them. Not deterred by this early setback, the government replicates the project. This time they figure that they can control the soldiers through a supercomputer called SETH (kind of like HAL in 2001, but smarter). But, as we all know, machines frequently break down. Pretty soon the computer comes to the conclusion that it's superior to humans and therefore it must destroy them. Uh oh, Van Damme to the rescue. [+]
