Late in the film, when Hoxworth confronts Reverend Hale outside the church, while the shot is on the Reverend, from behind Hoxworth, there is a bright sun shining on both men; in the reverse shots of Hoxworth, there is no sunshine and the weather is overcast.
During the initial journey from New England to Hawaii there is a heavy rainstorm but the skies are bright blue - no rain clouds.
When Abner watches the destruction of his church by the whistling wind after Malama dies, when the bell tower topples over, the rope used to pull it over can be seen.
When Abner and Jerusha approach their hut for the first time, there is a door covered with a net with a small open entrance next to it which they entered and found Iliki, but inside the hut, the small entrance can be seen next to a solid wall with no door.
Before Abner's sermon, a long shot of the ship shows a single man walking the deck. The next shot on board shows the deck filled with all the passengers.
In the opening scene, which is set in 1818, Jerusha is said to be 22, but a later shot of her gravestone has her born in 1799.
