Though she published no new writing of her own, Kael was not averse to giving interviews, occasionally giving her opinion on new films and television shows. In a 1998 interview with Modern Maturity, she said she sometimes regretted not being able to review: "A few years ago when I saw Vanya on 42nd Street, I wanted to blow trumpets. Your trumpets are gone once you've quit.” She died, in 2001, at her home in Great Barrington, Massachusetts from Parkinson's, aged 82.
Asked in 1998 if she thought her criticism had affected the way films were made, Kael deflected the question, stating, "If I say yes, I'm an egotist, and if I say no, I've wasted my life". Several directors' careers were profoundly affected by her, most notably that of Taxi Driver screenwriter Paul Schrader, who was accepted at UCLA Film School's graduate program upon Kael's recommendation. Under her mentoring, Schrader worked as a film critic before taking up screenwriting and directing full-time. Derek Malcolm, who worked for several decades as a film critic for The Guardian, claimed that, "If a director was praised by Kael, he or she was generally allowed to work, since the money-men knew there would be similar approbation across a wide field of publications". Alternately, Kael was said to have had the power to prevent filmmakers from working; David Lean claimed that her criticism of his work "kept him from making a movie for 14 years" (referring to the 14-year break between Ryan's Daughter in 1970 and A Passage to India in 1984).
