Ideal Husband, An Easter Egg - Where's Bunbury?

In the 1999 adaptation of Oscar Wilde's social comedy "An Ideal Husband" we hear someone call out "Come on, Bunbury!" as we cut to a shot of Rupert Everett playing a titled playboy who is playing cards in his posh club. As anyone who's a Wilde fan knows, "Bunbury" was the alias used by Algernon Moncrieff when he went to the country in Wilde's masterpiece "The Importance of Being Earnest"(which is seen performed in the movie along with Wilde himself). Here, "Bunbury" is one of the card players and he's played by none other than Oliver Parker, the film's writer-director!
