He's an astronaut, a rock star, a brain surgeon - he's a superhero! Who is described in such glowing terms this week? Is it, perchance, David Bowie, bearded art-lover and designer of bijou wallpaper? No siree, it's the hero of a rather marvellous video, The Adventures of Buckaroo Banzai across the 8th Dimension (Unique, pounds 12.99). A cult classic that originally appeared in 1984, it launched the careers of several of its actors: Peter Weller, Jeff Goldblum, Ellen Barkin and John Lithgow. The somewhat Aristotelian plot goes like this: Buckaroo Banzai is testing a new jet-propelled car when he crashes into a mountain, only to escape miraculously unharmed out the other side. Unfortunately, in the process he frees some evil black Lectoids (above right) from Planet 10, who have been imprisoned in the rock, and they set about trying to destroy the Earth. Cool. Will Buck, and his team of hard-rocking scientists, the Hong Kong Cavaliers, save the planet? Find out at your local video emporium, from Monday.
