Pat of the fun of being a sci-fi fan in the 1970s was that the success of Starlog magazine (which owed much of that success to the unprecedented popularity of Star Trek reruns in syndication combined with the one-two boxoffice punch of Star Wars and CE3K in '77) inspired a number of other publishers to flood the newsstands in the latter half of the decade with science fiction film magazines of their own. None of them matched Starlog in quality or longevity, unfortunately.
Another short-lived Starlog imitator was the awkwardly-titled Science Fantasy Film Classics, which had a four-issue run from late 1977 through 1978. The issue at the top of this post, the fourth and final issue, was the only one I ever bought, and unlike some of the other genre film mags of the era (Space Wars, I'm looking at you), it was in color and reasonably well-produced. (If I recall correctly, that Mattel "Code Name: Galactica" toy insert that I posted here a while back, originally appeared in this magazine.)
