Ready to get your geek on for the holiday season? Commedia Beauregard takes Charles Dickens’ classic holiday tale and adds a “Star Trek” twist with “A Klingon Christmas Carol,” which runs Friday through Dec. 13.

The Klingons — either in their original, evil goatee version or the bumpy-head ones seen later on ­—  stand only behind the Vulcans as “Star Trek’s” most popular aliens. For the adaptation, nearly the entire show is presented in Klingon (with English supertitles), a language developed for the series by Marc Okrand.

First produced in 2007, past editions of “A Klingon Christmas Carol” were one-night-only affairs. Popular demand has pushed it to a full run for 2009. Commedia Beauregard's recent productions have included plays translated from Polish, Spanish, Russian, German and, most recently, Czech.  Earlier this year they debuted a new translation of "R.U.R." by Karel Capek, the Czech play that invented the term "robot" in 1921.

The cast includes Michael Ooms as the Klingon Scrooge, Michael Bruckmueller, Kayla McCarthy, Robin Johnson, Erin Haynes, Laura Thurston, George Richard, Ben Chadwick, Alan Cloud, Neil Schneider, Kristin Foster, Lana Rosario, David Laux, Brian Watson-Jones and Andrew Northrop. It is directed by Sasha Walloch.

“A Klingon Christmas Carol” runs Friday through Dec. 13 at Mixed Blood Theater, 1501 S 4th St., Minneapolis. Tickets are $15 and $20. For information and tickets, call 612-338-6131 or go online.
