Proper DVD?
Although KILLERS FROM SPACE is in the public domain -- which is why virtually all the available prints of this movie are so crummy -- there was one VHS of it put out in the 90s that was a very good print. This was released by Englewood Entertainment and was part of the so-called Wade Williams Collection, a bunch of old, mostly p.d. films (sci-fi but many other kinds of films as well) for which Williams and Englewood had acquired mostly first-rate prints (though WW did mess around with several of these in some way -- including, for some unknown reason, using stills of the opening credits, rather than just showing the credits normally, on some).
Anyway, many of these titles have since been released on DVD from Image, almost all in excellent prints. But several -- including KILLERS, W. Lee Wilder's previous PHANTOM FROM SPACE, and some others (COSMIC MONSTERS, for instance) have yet to show up from this source. Image is still putting out some of Williams's titles -- the film noir THE WELL was one just released earlier this year -- so there's still hope that one day these other flicks, including KFS, will be given a reasonably pristine release. Maybe a nudge to Image might help.
If and when this happens I hope Image does NOT include one little device Williams insisted on adding onto the VHS: whenever Graves sees the alien's eyes in front of his face, Williams had the scene tinted green. As far as I can tell this was not in the original film (if it was, my apologies). It certainly adds nothing to the movie. Unfortunately Wade Williams has had a habit of mucking about with some of these films, adding "improvements" such as his awkward FX for ROCKETSHIP X-M and green "psychotronic" effects (whatever they are) in his version of CARNIVAL OF SOULS. Also, please restore the RKO logo at the end of the film, missing from his VHS!
