Michael Shanks, Claudia Black, and Cliff Simon star in a new audio series in 2012.

Stargate SG-1 and Atlantis audio book publisher Big Finish Productions has announced a third series for SG-1 in 2012, featuring the voices of Michael Shanks (“Daniel Jackson”) and Claudia Black (“Vala Mal Doran”).

Part 1 of Series Three will be released at the end of May, followed by Part 2 in August. Each part will run approximately three hours in length, and run £25.00 for three CDs or £20.00 for a digital download.

Here’s how Big Finish describes Part 1:

A shooting in the heart of Stargate Command is only the beginning for Daniel Jackson and Vala Mal Doran. Suddenly it’s friend against friend, none of their allies can be relied upon and they’re the universe’s only hope to foil the latest scheme concocted by the last System Lord, Baal. Will Daniel, Vala and a few of Vala’s less than savoury friends be enough to stop a conspiracy that reaches deep into the heart of Stargate Command and threatens to destroy everything they’ve spent years building?

Other voice actors this year include Cliff Simon (“Baal”), John Schwab (“Major Hunter”), Andrew Collins (“Keto”), Stephen Hogan (“Olssen”), Susan Franklyn (“Rix”), Alex Mallinson (“Airman/Robot/Jaffa”), Paul Hyu (“Lt. Colonel Yin”), Andrew Whipp (“Zoder”), Regina Reagan (“Wellan”), Anna Tolputt (“La’rath”), and John Banks (“Korek”).

Authors include James Swallow, Sally Malcolm, and Steve Lyons (Part 1), and Peter Evans, Richard Dinnick, and Sharon Gosling (Part 2), with direction from Lisa Bowerman and Jason Haigh-Ellery.

So far the publisher has not announced any stand-alone title for the story (or stories) — just “Stargate SG-1: Series Three.” With six hours of total production time, it could be that each half of the series will be comprised of three individual, hour-long stories (as with past series).
