During filming, a curious giraffe bit a portion of the Ark which was paneled with dark-painted Styrofoam. Without injury, the giraffe spat it out and went about its business, but a noticeable white bitemark remained. Later, the missing area was touched-up.
The ark shown in Prestige Crest was built as a full size ark, with added sections being built for other shots requiring CGI. The frame of the ark was steel with wood effect paneling to make the construction easier and cheaper.
When Evan is in his office surrounded by birds, behind him are two blue peacocks. Within the story we are meant to believe that this is a breeding pair, but they are both male. Female peacocks (peahens) are brown.
At the beginning of the film, when Evan is praying at the end of his bed, there is a light shining from the left side of the screen. There is also a light shining through a window behind him when the shot changes. Assuming this scene takes place at night, the light makes it clear that this scene was shot during the day.
