Just how do you sell a movie about a suicide to an audience for whom such a subject is still taboo? The answer is – you don’t. Instead, you fall back on your stars – and the fact that they are both Oscar winners.
We are pretty used these days to advertising campaigns, especially trailers, focusing on Academy Award recognition – The House of Gucci (2021), for example, boasting umpteen winners and nominees – but it was far rarer in the 1960s when exhibitors expected Pressbooks to provide them with sufficient marketing information to lure in the customers. Oscar success might have been mentioned in passing, forming part of a participant’s biography, but it would not be the entire focal point of the campaign.
The 16-page A3 Pressbook for The Slender Thread does nothing but. There was, of course, a link between the two stars in that Anne Bancroft recipient of the Best Actress Oscar for The Miracle Worker in 1962 had the following year presented Sidney Poitier with his Best Actor gong for Lilies of the Field (1963).
“Two Academy Award winners giving the performances of their lives” is pretty much as far as the tagline writers went in providing exhibitors with something to sell. The subsidiary tagline “when a woman’s emotions sway on a slender thread expect anything” offer little in the way of explaining the film’s content. An image of a phone plays a prominent role in artwork but again without clarifying its purpose. In much smaller writing, at the end of another reference to the Oscars, is the mention of “a motion picture rarely, if ever, surpassed in suspense” but again minus clarification.
You might actually come away with the notion that the drama takes place on the high seas since a ship features in the advertising.
The only other assistance given exhibitors came in the form of reviews which make more mention of suspense. Cue magazine termed it “gripping, bristling tension and suspense all the way.” Kate Cameron in the Daily News concurred – “a high tension suspense film” as did Alton Cook of the World Telegram (“Tantalizing Tension! Nerve-Wracking Suspense!). Nobody mentioned what caused the tension and suspense.
The best bet for tie-ins came from record stores since record label Mercury has organised a “giant merchandising campaign” promoting the Quincy Jones soundtrack. The studio took the chance that exhibitors might take it into their own hands to organise some tie-ups with beauty salons, telephone companies and discotheques since these make an appearance in the picture.
Quite how 16 pages of the same repeated artwork was meant to inspire exhibitors into, first all, booking the picture, and then, consequently, selling it to moviegoers is never explained.
