i have always like this john frankenheimer film . good script by elmore leonard and the main reason this wasn not just another thriller be because of frankenheimer . his taut direction and attention to little detail make all the difference and he even hire porn star ron jeremy a a consultant . you can make a case that it the last good film roy scheider make . i have always say that robert trebor give just a terrific performance . clarence williams iii get all the publicity with his scary performance and he excellent also but i really think trebor stand out . frankenheimer may not be a proud of this film a others but it be an effective thriller full of blackmail and murder and sex and drug and and real porno actor appear in sleazy part . what can you say about a film that have ann margaret be shoot up with drug and rap . a guilty pleasure to say the least . vanity have a real sleazy role and a very young kelly preston make an early appearance . a classic exploitive thriller that shouldn not be forget .
