An Ideal Husband (1999)

Continuity mistake: Right after the debate in the House of Commons, Robert talks to Gertrude in the hall way. Behind them is a statue head. Several shots later that statue head magically moves to the opposite wall where Arthur "talks" to it.

Continuity mistake: Before the party scene, there's a little musical montage where all the occurs can be seen getting dressed. There's quick second long shot of Lord Goring, played by Rupert Everett, placing a bright red flower in his buttonhole. A few seconds later, he's placing a white flower in his button hole. Its really quick but it unmistakably Lord Goring.

Continuity mistake: When Lord Goring and his father are riding through the park in a carriage, Sir Robert is talking but his lips don't move and/or move out of sync. with the dialogue.

Trivia: The play that all are watching when Lord Goring fools around with his looking glass and Gertrude asks Robert what his business with Mrs. Cheevley is, is "The Importance Of Being Earnest" by Oscar Wilde. In the end you see the author coming out on the stage and saying a few funny words. This really occurred at the premier, Oscar Wilde did really say these things. It is a kind of play in a play, as "An Ideal Husband" was also written by Wilde.

Lord Arthur Goring: To love oneself is the beginning of a lifelong romance.

Lord Arthur Goring: I am glad you have called. I am going to give you some advice.
Laura: Oh pray, don't. One should never give a woman something that she can't wear in the evening.

Lord Caversham: Married yet?
Lord Arthur Goring: Ask me again in half an hour.
