Battlestar Galactica

As in the previous episode, some of the guns used in the algae planet scenes were loaded with balls of dust. The impact of the dust balls helped to simulate the impact of real bullets.

Grace Park read the "Previously on Battlestar Galactica" line at the beginning of this episode.

As of the beginning of this episode, there are 41,401 survivors, one fewer than at the beginning of the previous episode.

As in "The Eye of Jupiter (1)," the scenes on the algae planet in this episode were filmed in Kamloops, British Columbia, off East Shuswap Road. The location was chosen for distinctive geological features like the hoodoos (tall, thin spires of rock of varying thickness said to resemble a totem pole). Kamloops (in south-central British Columbia) is relatively close to Vancouver, where most scenes of the series are filmed.
