Desk Set (released as His Other Woman in the UK) is a 1957 American romantic comedy film starring Spencer Tracy and Katharine Hepburn.

Methods engineer and efficiency expert Richard Sumner is the inventor of EMERAC ("Electromagnetic MEmory and Research Arithmetical Calculator"), nicknamed "Emmy," a powerful early generation computer (referred to then as an "electronic brain").

Bunny's fear of unemployment seems confirmed when she and everyone on her staff receive a pink "layoff" slip printed out by a similar new EMERAC already installed in payroll.

Parts of the EMERAC computer, particularly the massive display of moving square lights, would later be seen in various 20th Century Fox productions including both the motion picture (1961) and TV (1964–1968) versions of Voyage to the Bottom of the Sea and the Edgar Hopper segment of the 1964 film What a Way to Go!.

[7] The New York Post review was mixed: "There are such sops to sentiment as Miss Hepburn's willingness to be dragged altarwards by the young head of her department, Gig Young, who kindly lets her do her most impressive work, and a growing understanding between Hepburn and the rather remote and intellectually Olympian Tracy....Running true to form, the sex narrative follows a predictable pattern, rewarding honest virtue and slapping down the unworthy, and the other, scientific trail is permitted a twist that may surprise any who have found themselves emotionally involved in that timely problem of technological unemployment....'Desk Set,' let us conclude, is a shining piece of machinery brought to a high polish, and, delivered with appropriate performances, flourishes.

The word: one of those electronic brains could do the job much better and with less back chat—and what's more, it would free the girls' energies for the more important job of getting a man....Desk Set has been expanded [from the play] by a sizable pigeonhole, in which [Hepburn and Tracy] intermittently bill and coo....On the whole, the film compares favorably with the play....And though Actress Hepburn tends to wallow in the wake of Shirley Booth...she never quite sinks in the comic scenes, and in the romantic ones she is light enough to ride the champagne splashes of emotion as if she were going over Niagara in a barrel.

Equipped with an insubstantial vehicle, bogged down by surprisingly flat-footed direction...the stars come close to being embarrassing as they bound through roles involving them in office nonsense about a mechanical brain, a bibulous Christmas party, an innocent, but suspecting, dinner in negligee Katie's rain-bound flat....Marchant's foolish little comedy gains nothing via the Phoebe and Henry Ephron adaptation.

Long recitations from "Hiawatha" and "The Curfew Shall Not Ring Tonight," plus question-and-answer games...in addition to the repetitiousness of the central idea...turn 'Desk Set's' 104 minutes into an endurance contest for cast and audience.

The site's consensus reads: "Desk Set reunites one of cinema's most well-loved pairings for a solidly crafted romantic comedy that charmingly encapsulates their timeless appeal".
