The film ends with a news report of Rupert's crime, his six-year prison sentence and parole after two years, set to a montage of storefronts stocking his "long-awaited" autobiography, King for a Night, which states that Rupert still considers Langford his friend and mentor and that he is currently weighing several "attractive offers," including comedy tours and a film adaptation of his memoirs.

One interpretation of the ending is that it represents Rupert’s ultimate triumph over adversity. Despite his questionable methods and criminal behavior, he managed to achieve fame and recognition in some form. The crowd’s adoration can be seen as a validation of his relentless pursuit of success.

One interpretation is that Rupert’s prison cell performance represents his ultimate escape from reality. Throughout the film, he struggles with feelings of inadequacy and rejection. By imagining himself as a successful comedian performing in front of an adoring audience, he can momentarily escape the harsh realities of his life.
