It's probably not possible to improve upon Oscar Wilde, but Anthony Asquith's 1952 film adaptation of The Importance of Being Earnest makes a good show of it. The few additions work, and the subtractions...well I don't want to call the witty dialogue redundant or unnecessary, but it's not exactly missed. Improved? Probably not. But certainly well met. Pat and I talk about those edits and a lot more on this week's Lost in Criterion.
