Make no mistake, it was still the 70s in July 1981, when those infamous murders occurred on Wonderland Avenue in the Hollywood Hills. Well, we’re told the murders are infamous, as brutal as Charles Manson’s rampage 12 years earlier, though I’d never heard of them. But never mind: Brutal, bloody murder, infamous or not, is good for movies. Even better is when drugs and sleazy nightclub owners and former porn stars are involved, which is of course the case with *Wonderland,* James Cox’s hyperkinetic, retro-groovy, and sorta superfluous deconstruction of the crime.
