In a review of The Late Shift for The New York Times Book Review, Jon Katz wrote, "[This] is a reporter's book, unfailingly balanced, thoroughly researched, filled with scoops and fresh details. Even though CBS's wooing and winning of Mr. Letterman was the subject of enormous publicity, Mr. Carter's book makes clear that we knew less than we thought about what was really going on." Katz criticized the book for not going into more depth about Letterman's switch to CBS, writing, "As readable as it is, 'The Late Shift' needed to take a more critical, detached look at the long-term significance of Mr. Letterman's move. A number of questions are not addressed." He concluded, "'The Late Shift' is nonetheless a powerful story, and ultimately a sad one, filled with casualties as well as winners. Mr. Leno, who has been made to seem a second choice by the very people who elevated him, has been betrayed by his employers in the most basic of ways, and he has not yet recovered." Kim Campbell reviewed the book for The Christian Science Monitor. "More than just a play-by-play account of the actions that followed Johnny Carson's 1991 retirement announcement, Carter's well-written book is a look at the history of the late-night franchise, and of the men who host the shows that we would rather watch instead of going to bed." Campbell described the book as revealing in its assessment of NBC's decision to pass over Letterman for The Tonight Show, concluding, "Carter's eye-opening book leaves the impression that NBC will be remembered more for its loss of Letterman, than for its role as creator of late-night television." Lawsuit Helen Kushnick, Jay Leno's manager at the time of Carson's retirement who was pushed out following her heavy-handed tactics, filed a $30 million lawsuit against Bill Carter, claiming libel. Specifically, her case related to a claim that she planted a story about Carson's retirement in a New York City tabloid. The then-pending lawsuit was noted in the closing credits of the film, as the Broadway tune "There's No Business Like Show Business" plays. The lawsuit settled out of court for an undisclosed sum; Kushnick died of cancer in August 1996. Film adaptation A film adaption of the book was produced in 1996 by HBO, directed by Betty Thomas, and starring John Michael Higgins as Letterman and Daniel Roebuck as Leno. The film received seven Emmy
