Bridget Jones and Jane Eyre?

I've just seen Bridget Jones's Diary - once again and for the 20th time in my life. I wanted to spot scenes from Pride and Prejudice so as to revisit the book in a fun way, but I found something interesting which i'll do some research on. By the end of the film, Bridget changes the name of her diary 'Bridget Jones's Diary' for 'Diary of Bridget Jones: Spinster and Lunatic' and I think that this might be an allusion to Jane Eyre. In a very similar masochist act by the middle of the novel, Jane Eyre paints a portrait of herself - a representation of her inner and outer self - and gives it the title 'Portrait of a lady, disconnected, poor and plain.' I think that we can find a parallellism not only between the autobiographical nature of both Bridget and Jane's work - their diary and portrait respectively - but also between the grammar used in the titles of both objects. I-m not sure whether this is a blink to Charlotte Bronte's novel but I'll try to find out and discuss this with BJ's fans.
