What is “human?” That’s the basic question posited by Ridley Scott’s visionary science fiction opus, release in 2007 in a 25th-anniversary “final cut,” the director’s third pass at the film.

Based on a novel by Philip K. Dick and set in the dark, rain-soaked Los Angeles of 2019, the tale follows “blade runner” Deckard (Harrison Ford) as he pursues and attempts to terminate four “replicants” – genetically-engineered humanoids – who have violently escaped an off-world colony and returned to earth. Deckard becomes increasingly conflicted about his murderous job and doubtful about his own identity, as he falls in love with a replicant (Sean Young) and begins to realize that his prey may be more human than he believed.

I will always passionately love Requiem for a Dream. I will always passionately love Requiem for a Dream more than The Fountain. But I can't really compare Darren Aronofsky's two latest releases; it simply wouldn't be fair! The Fountain is a challenge that takes on a re-definition of science fiction, attempting to span 1,000 years and intersecting three parallel stories. It is certainly a task to admire. Aronofsky searches life's biggest questions - love, death, spirituality, existence - all while trying to go beyond typical science fiction films that were plot-driven by technology and science. He notes, "the interesting things are the ideas; the search for God, the search for meaning."

The Earth was accidentally demolished to make way for a hyperspace bypass, and archetypal English bloke Arthur Dent was left hitching around the Galaxy with just his bathrobe, a towel, and a copy of the Hitchhiker's Guide (the one that has "Don't Panic" in friendly block letters on its cover.)

Welcome to the first full-length cinematic version of this 1980s sci-fi icon. And, since author Douglas Adams himself wrote the script, there is no reason to panic! The film is mostly harmless - eh, make that mostly delightful. Special effects range from a spacecraft that looks like a cannister vacuum cleaner turned inside out, to aliens from the Hanson Workshop who look like giant beanie babies. But the tour of the "factory floor" of Megrathea, the planet that manufactures worlds, is worth the price of the DVD. Adams included many of the skids, anecdotes and one-liners which made the book so special, and had them discreetly animated as well.
