The best way to find out about that would be to submit a question to them about it as part of the "Ask Eddie" effort. If it gets through the screening process, some information/perspective about it on their end might well emerge.
I think all collectors have the same wretched copy of the film, which has made evaluation of its overall quality more than a bit daunting. It's been at least a dozen years since I pulled out my copy. What we know is that it was clearly a "B" unit effort from Universal; the scriptwriter (Gene Levitt) worked mainly in television, both before and after this project; the film boasted a highly-regarded cinematographer in George Robinson. Despite widely varying opinions about the film's overall quality, the performance of Ray Danton in the lead role is consistently praised for its low-key sensitivity. The late Mark Fertig was not too keen on the film at his WHERE DANGER LIVES blog--that review, along with another film featuring Danton, will eventually surface here as we move chronologically through the writings there.
