SGA S4 Spoilers: Casting for "Tabula Rasa"


The following includes casting spoilers for Season Four’s episode, “Tabula Rasa”, written by Alan McCullough.


Executive Producer and co-showrunner Joseph Mallozzi has been writing about the various stages of production for Season Four of Stargate Atlantis in his personal blog. Once in a while, he’ll drop hints about each of the episodes, such as working title, casting, or set design. He also provides pictures from his visits to the set and other departments. In his April 23 entry, he mentioned casting for “Tabula Rasa”.

Not much is currently known about “Tabula Rasa”. The title is Latin for “scraped tablet” (which has also been translated to mean “clean slate” or “blank slate”). Writer McCullough finished up his final draft around March 21 and they are now shooting scenes. As far as plot is concerned, Mallozzi hinted on March 22, “We discuss Alan’s Tabula Rasa rewrite. How could Lorne top his barefoot scene in Doppelganger? Well how about this meaty role? Oh, and poor Katie.”

Zach Selwyn

As far as casting is concerned, Mallozzi talked about finding the actor for “Scientist #2”:

Zach Selwyn was on the lot today. For those of you not familiar with the larger-than-life host of G4’s Attack of the Show, he is the star of a SGA rap video that took youtube by storm. In fact, Zach rapped and danced his way into a guest-starring role as episode linchpin Scientist #2 in season four’s Tabula Rasa. His big scene is tomorrow, first up! I wished him luck and assured him that, as much as I would love to watch his early morning performance, I’m the victim of a rare medical condition that necessitates my sleeping in past 7:30 a.m. every morning. Despite the fact that he was celebrating his birthday, he did come in to interview cast members for his show and, God knows why, thought it might be a good idea to interview me as well (a decision, I’m certain, he now deeply regrets). Still, since we were shooting the interview on Stage 3, I did manage to snap some pics of the Daedalus.

Zach Selwyn was born April 23, 1975 in Tucson, Arizona. Some of his previous television acting appearances include Chicago Hope, Sabrina, the Teenage Witch, and Dragnet. He is not only an actor, but also a composer, screenwriter, and a country-rock musician in Los Angeles with his band “Zachariah and the Lobos Riders”.
