The longest kiss in movie history, clocking in at six minutes, is featured in the film "Kids in America" (2005).
While other films showcase notable kisses, such as the groundbreaking age-gap kiss between an 80-year-old and a man in his 20s in "Harold and Maude" (1971), none surpass the duration of the kiss in "Kids in America." The length of the kiss in "Kids in America" distinguishes it as the record holder. It is important to note that what constitutes the best kiss versus the longest kiss is a matter of opinion, based on acting performance and the storyline. However, in terms of verifiable duration, "Kids in America" holds the title.
