1. Colin firth's character name is Henry Dashwood. 2. The women playing his fiancee is one of Binley's sisters from the P&P mini 3. Mr. Dashwood's house looks like Pemberly from the mini. 4. The fiancee's daughter played Mrs Elton in the BBC mini of Emma and played one of Mr.Binley's sisters in Lost in Austen.
Not only did Anna Chancelor play Miss Bingley in Pride and Prejudice, but Colin Firth played Mr Darcy in the same one. She lost him to another woman twice :)
Also, the scene where they're looking at the portraits, there is a Field Marshall Bingley Dashwood.
And a crazy stretch, but the hotel Ian works at, the Great Britain Grand Hotel, was the apartment building Bridget Jones lived in. And Bridget Jones's Diary is based on Pride and Prejudice. And makes many references to Colin Firth and his wet white shirt scene.
Interesting that mother/daughter Glynis and Clarissa were both Miss Bingley.
