Revealing mistake: When Jack and Algy are singing "Lady, Come Down" to try to get the women to listen to them again, the above shots of Algy playing the piano do not match the music being played. He scarcely even seems to try to make it look real.
The Importance of Being Earnest (2002)
1 revealing mistake
Directed by: Oliver Parker
Starring: Colin Firth, Reese Witherspoon, Rupert Everett, Frances O'Connor
Continuity mistake: When the women ride by on horseback in the woods, once they pass the men, they've switched sides. (01:05:38)
Lady Bracknell: Sorry if we are a little late, Algy. I was obliged to call on dear Lady Harbury. I have not been there since her husband's death. I never saw a woman so altered. She looks quite twenty years younger.
Trivia: Rupert Everett ad-libbed two scenes: the one in which he kisses Colin Firth on the cheek, and the one where he heartily slaps Colin Firth on the bottom. The director, Oliver Parks, thought Firth's startled reactions were so funny that he kept both in the film.
