When the floating dry dock Annie is to take to Alaska is first seen in a long shot, it is full of other small ships. In the next shot from aboard the dry dock, its deck is empty.
Early in the movie, a scene is shot at Alec Severn's office and the character's first name is incorrectly spelled (Alex) on the front door.
Near the beginning of the film as Annie descends the stairs from the bridge of her tugboat, a moving shadow of the boom microphone is visible on the deck hatch in front of her.
