According to the comments at IMDb, this is not as weird that it may seem - the film is a joint US/French/Spanish production, and Mortensen speaks prefect Spanish (!), albeit with an Argentinean accent. The trailer, though it has no sound (if you find one that does, let us know - all the sites I've found have the same one), looks amazing - warfare, dueling, rapiers, and lots of Viggo close-ups for the ladies. Plus, the first sentence of the book's summary at Amazon contains the word "swashbuckler," which is very promising indeed. Frustratingly, Alatriste isn't scheduled for a US release until next December - I sure as hell hope we can at least get a trailer with some audio before that.
