Two of Us

The director originally planned to shoot in a multi story hotel. The original drafts of the screenplay were based on this premise, with major scenes taking place in elevators, stairways, an underground garage, an indoor bar, and an outdoor pool. However, at the last minute the hotel location was lost. The screenplay then had to be adjusted to fit the new location, a one story resort where most of the movie takes place.

The two main characters are trying to be quiet, trying to be very careful to avoid zombies, but in one scene they bath in a stream, laughing, having fun, without their protective weapons nearby. This seems out of character related to their previous efforts to be careful.
