Redress
In film, a redress is the redecoration of an existing movie set, so that it can double for another set. This saves the trouble and expenses of constructing a second, new set, though they face the difficulty of doing it so the average viewer does not notice the same set is reused. Also there could be logistical problems, such as conflicting shooting schedules, continuity if the set is not quite the same as it was (if it should be the same) or different (if it should be). The latter problem arises because the set dresser may be unaware of changes created by the action.
Examples
A good example of a successful redress occurred in the film Star Trek II: The Wrath of Khan where the bridges of the Enterprise and the Reliant were filmed on the same set. Some of the reasons for its success are as follows:
All the scenes on the Reliant bridge were shot after the scenes on the Enterprise bridge, eliminating difficulty with continuity and conflicting shooting schedules. Only one actor, Walter Koenig, had to be present on both the Reliant and the Enterprise.
