Before eHarmony

If I were to create "How I Met My Husband" into a feature length film (which would blow apart the box office) I would change a few things.
Characterization
While the roles of the characters would remain as they did in the story I would expand the character role of many people. First Lorretta Bird would become more of a main character. For example in the part of the story where Edie is trying on the dress, the scene would flash to Lorretta meeting Alice in town. Of course this trip in town would portray all of Loretta's annoying habits. The idea would that Lorretta would be the stereotypical goofy character to making this romantic movie into a romantic comedy (similar to Betty White's character in "The Proposal"). Also Alice would be a bit more stalker-ish than she is in this story.
Plot
The plot would remain more or less the same, although in addition to the added town scene. I would also add a scene that shows a flashback to Chris and Alice's relationship. Also there would be a scene of present day Edie and her husband, with Edie's husband saying things like "and your mother would wait for me at the mailbox everyday" and Edie would agree with him, but the movie viewer would then see the entire story (later in the movie). This scene would occur at the very beginning. I think the addition would explain the point of view of this story a bit better.
Point of View
The point of view would remain the same in this movie, the irony of the story would not work out any other way. So Edie would continue to drink her Ginger ale with ice cubes.
Setting
I envision a more modern (perhaps 1950s or 1960s) instead of the 1920s-1940s this story is set in. That way I can have cheesy 50's songs playing the background (for example "Hound Dog" by Elvis). These songs don't really add anything other than a cheesy factor. Which would make this movie swing into more of a comedy than a chick flick.
This story really would only need some additions to it, the story itself is okay. Chris would still be a nomadic bachelor and Edie would remain a naive child. The climatic scene (where Alice accuses Edie of having sex with Chris) would remain very close to what was written, and Mrs. Peebles would save the day.
