Looking at this trailer, despite never having read the book by Alexandre Dumas, I get the feeling that this movie isn’t going to be the least bit faithful–except in a very surface manner–with the novel that it’s supposedly based upon.
This makes me wonder why it’s even be called ‘The Three Musketeers,’ as opposed to something like: “Three Or Four Good Guys With Swords Who Fight Against Incredible Odds Yet Somehow Manage To Get Out Without A Scratch” or perhaps “Using The Name Of A Classic Novel So That I Can Put My Hot Wife In A Movie Based So Loosely On The Aforementioned Novel That I Could Call It Just About Anything And No One Would Really Notice The Difference”
Neither title leaps off the page, but at least they’re honest.
By the way, what’s with the aerial shots, and why do I get the feeling that this movie is going to be a bit steampunk?

Haha. I like your other titles, though I feel like they’d be quite a mouthful. It’s a little sad the way they use known names to sell the movie when it’s basically unrelated. Did you know the 3rd and 4th Die Hard movies were just regular movies, but they rewrote them to star John McClane so that they’d sell better? Oh well.

Yeah. If I recall, “Die Hard With A Vengeance was based upon a novel called “Simon Says.” My whole thing is, if you’re going to change what most consider to be a classic work of literature, be a least a bit innovative.
Move it to the present, or even the future; make it with gang members (like Walter Hill’s “The Warriors” was , if I recall, based loosely upon the Battle of Thermopylae) but don’t keep it time period accurate, then decide to throw in all sorts of nonsensical details.
