“This Is Spinal Tap” shines a light on the self-contained universe of a metal band struggling to get back on the charts, including everything from its complicated history of ups and downs, gold albums, name changes and undersold concert dates, along with the full host of requisite groupies, promoters, hangers-on and historians, sessions, release events and those special behind-the-scenes moments that keep it all real.
Lord Rayden (Christopher Lambert) handpicks three martial artists — federal agent Sonya Blade (Bridgette Wilson), Shaolin monk Lui Kang (Robin Shou), and action movie sensation Johnny Cage (Linden Ashby) — and mentors them. After intense training, Rayden transports the trio to Outworld, the site of an inter-dimensional fighting tournament. There, the three humans must defeat the demonic warriors of the evil Shang Sung (Cary-Hiroyuki Tagawa) — or allow Sung to take over the Earth.
In a distant galaxy, planet Spaceball has depleted its air supply, leaving its citizens reliant on a product called “Perri-Air.” In desperation, Spaceball’s leader President Skroob (Mel Brooks) orders the evil Dark Helmet (Rick Moranis) to kidnap Princess Vespa (Daphne Zuniga) of oxygen-rich Druidia and hold her hostage in exchange for air. But help arrives for the Princess in the form of renegade space pilot Lone Starr (Bill Pullman) and his half-man, half-dog partner, Barf (John Candy).
