Sometimes, actors join a project to fulfill creative desires, drawn to material that offers newfound areas of dramatic expression, challenging them to reach beyond their capabilities and establish new career achievements. Other times, actors just want a free vacation. I believe the latter was the primary motivation for the cast of "Killer Force" (titled "The Diamond Mercenaries" on the disc), sending famous performers to the arid wilds of South Africa, spending their days rolling around in the sand, shooting guns, making out with Maud Adams, and blowing up various vehicles. Not that there's anything wrong with a chance to visit a corner of the globe, but "Killer Force" could've used more narrative emphasis when constructing its tale of a heist gone wrong. Visually, it's a stunning picture, taking advantage of its unique locations, which provide a wide playing field for criminal activities, but storywise, the effort is missing some snap with its twists and turns, in need of more combustible events to ornament this agreeable but unremarkable thriller.
