More on Mr and Mrs SmithCreative Screenwriting has more on Mr. and Mrs Smith. A good read, particularly if you want to understand how these things start (often what they don't really cover in special features).
In a nutshell, it's this:
"For a project that started out as screenwriter Simon Kinberg's thesis for his Columbia University graduate film school class (based on what a friend told him about the intricacies of marriage therapy), Kinberg developed an amusing assassin/marriage flick, structurally alternating between an action-based narrative thrust and act-break fragments from the couple's counseling session. When Kinberg came to the attention of screenwriter/producer Akiva Goldsman (A Beautiful Mind), the two teamed up to pitch the project around town and eventually set it up into the star-driven summer vehicle Mr. & Mrs. Smith has now become."
I've come to the answer for a question I've had for a while about some movies: "Why would someone write this?"
When I'd only seen the trailer, it just looked like violence, mayhem and beautiful people. It looked pointless except for a cheap thrill.
I can understand why there's a demand for that, but knowing a bit about the writing process, I can't understand why people put the time and effort in to make some movies.
Mr. and Mrs Smith is not in that category any more. It's got a message worth telling, and that is that marriage is worth fighting for.
That's what I like about movies: the truth is usually out there somewhere.
