Our good friends, Scott & Miles, at The SciFi Diner Podcast just posted their interview with Klingon language creator Marc Okrand. Recorded at the most recent Farpoint Convention, Scott & Miles got to spend time with Mark and talk about his experiences in the Trek universe as well as his time working Disney's Atlantis, creating the Atlantean language.

About Mark (from episode description)

Originally released in book form in 1996, "Star Trek: The Klingon Way, A Warrior's Guide" is now available for your Vulcan Klingon ears. Narrated by both Michael Dorn (Worf: TNG) & Roxann Dawson (B'Elanna Torres: VOY), the audio version is abridged (unfortunately) and will set you back $6.95 (or free with a new account) from Audible.com. Many of you know "The Klingon Way", penned by Marc Okrand as a collection of adages, in Klingon and English, for contemplation by the "meeker races".

In an interesting article written for the NY Times, columnist Ben Zimmer dives deep into SciFi constructed Languages and discusses the upcoming  film "Avatar".

The new James Cameron flick features a fully constructed language for the  blue skinned, feline like creatures featured in the film.  Jimmy Cameron and his normal out-spoken ways even went so far as to say that the Na'vi language will out-klingon Klingon.

Cameron clearly had Klingon in mind when he began envisioning the linguistic landscape of “Avatar.” About three years ago, he hyped Frommer’s development of the Na’vi language by boasting to Entertainment Weekly that it would “out-Klingon Klingon.” Frommer now dismisses this as a bit of Cameronian hyperbole, assuring me that he has nothing but respect for Okrand’s masterwork. In fact, Frommer got the “Avatar” assignment in part on the strength of his work on “Looking at Languages,” an elementary linguistics workbook that includes a student exercise in deciphering Klingon word order. (Klingon follows the unusual object-verb-subject ordering.)

Also featured in the article is the father of the modern Klingon language Marc Orkrand.
