Pre-introduction Update.
I also suggest you check out this post (and then this one) at my regular blog for a look at the fantastical art of Gary A. Viskupic, one of the illustrators for those very same 70's TV listings...
Medium Fun and Games: The Newsday Reviews of John Cashman
"Thanks for this! I grew up reading Newsday and remember Cashman's byline. Nice tribute!" -Shawn Levy, film critic (The Oregonian)

Q. I am a middle aged housewife who has never written to a newspaper or magazine before, but I am being forced by my family to do so. The best part of your whole newspaper is the movie reviews in the TV section. We are constantly reading them to each other. Some are the best comedy writing I have ever read. We would love to know who writes them, and also see a picture of him. Please tell us something about him. Please thank him for the fun and laughs he brings to our home each week.---C.K., Dix Hills.
A. Though the Phantom Reviewer thanks you for your kind words, he continues to refuse to reveal his identity. But we conspired with the Newsday art department to get a rendering of the Phantom for you. One of the artists sneaked a peek at him the other day while he was asleep at his desk (he'd watched movies all night) and he awoke and, well, see above.
Continuing to search through the books, the December 8th, 1974 issue at last answered the big question, which was still coming in from readers:
The Phantom Reviewer has finally decided to throw off the cloak of anonymity and reveal himself as the flesh and blood author of the wit and wisdom that has given readers so much pleasure. He is Newsday staffer John Cashman. Formerly day Nassau editor, John spent last year in California on a Stanford University fellowship and is now an Ideas writer, kibitzer and all-around pussycat. John, who was previously a columnist and has authored two books, is married and the father of four children. He has been going to the movies seriously for more than 35 years and has, thus far, written more than 4,000 movie reviews for the TV Book.
So that answers who he was, but not what became of him. If anyone has information, let me know...
In any case, it was Cashman's droll reviews that inspired my tribute. They're often clever and funny, but more importantly to the format, they're brutally succinct. Sometimes there's a damning-with-faint-praise quality to them, as with this one of 1944's The Purple Heart: "Dated and embarrassing, but not bad of that ilk." Some reviews are damning with their ambivalence, such as the "Not good, not bad" earned by 1941's Honkytonk. I have so far found twenty-eight films described as "sitthroughable." He also delights in consistently pointing out the prettiness of Rhonda Fleming, and the unprettiness of Vera Hruba Ralston. (I've also found nine separate references to Alan Ladd taking off his shirt, but that's a topic to ponder another time.)
Another reason I love reading these reviews is that they recall an era when you never knew what treasure you might find among the meager offerings on your handful of channels. Many of the movies I'll list here probably haven't seen the light of the little screen in years, except perhaps on Turner Classic Movies, or mutilated and mired in commercials on AMC. Happily, some live on as experiments of "Mystery Science Theater 3000." And I recently acquired one, Creature From the Haunted Sea, in a DVD set of 50 horror movies for $15.99 at Big Lots along with many other public domain-type cinematic ephemera. (To quote a familiar Cashman line, it's even worse than it sounds.)
Cashman sometimes throws in obscure names or leaves you hanging with trivia that you would then have to see the film to figure out. (Of course, these days you can just look up South Sea Sinner on IMDb to see just who that piano player is, or Google "Abner Biberman"... )

Abner Biberman.
Although I normally limit my childhood nostalgia collection to items from the years 1974-1983, I did purchase a Newsday TV guide from 1984 a while back. It strangely summed up why my fond recollections end around autumn '83. Well, certainly there's my entrance into public high school, an unceremonious end to the fun and hijinks of Catholic grade school. But I see there are no more cheesy horror and sci-fi flicks on Saturday mornings and afternoons. Indicating an end of innocence, if you will, the genre listing "adult" pops up frequently, where it had very rarely appeared in the older, mostly cable-free guides. And, worst of all, due to those new channels growing like kudzu, the reviews are strangled into one-line, snark-free encapsulations. (The 1973 TV movie A Cold Night's Death, for example, is summarized thusly: "Two men are isolated.")
It was a new era alright, ushering in endless showings of bland Hollywood blockbuster slop and made-for-cable crap, while effectively discarding anything in black-and-white or made over twenty years ago.
While I would love to compile Cashman's work completely, I am for now sticking to the much easier task of just including the funniest or most trivia-laden reviews. If one doesn't interest you, keep reading--the next may have you laughing out loud. While it may seem from this collection that he delighted mainly in eviscerating the dross of Hollywood's output, I assure you he was, foremost, a movie lover.
2/23/08 update: I have revised the blog so that you must use the menu on the left to navigate through the reviews. I've done this because my sitemeter shows people visiting the blog daily, but no visitors or visitation time actually recorded. This is because the meter only registers a visit after the user clicks on a second page. With all the reviews on the first page, no second page is clicked, thus no visit recorded. I haven't added any new reviews in a while, but I hope to in coming weeks. The most recent additions are titled in blue.
