 All of Vala's voiceovers in that episode were filmed beforehand so that the director could pick which parts would be voiceover and which parts would be shown.Since the environment of Vancouver, British Columbia, Canada, where "SG-1" and "Atlantis" were primarily filmed, was being developed, shooting locations were getting rarer for new offworld stories.The producers countered this with a new reusable village set, with almost 280 feet (85m) in length and 12000 sqfoot (1100 m²) in area, the biggest they ever built.
