Cover Set

What this is about

For it to work, it has to be genuinely ready, not theoretically available. The set is dressed, the scenes are broken down, the cast for those scenes is called or reachable, and ideally the space is close enough that the switch is not a company move. The first AD makes the call early in the morning against the forecast, and the call sheet may already list both plans. Studio and stage productions get this almost for free; location work has to pay for a second dressed space to stand idle.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

Where this differs from the general case:

• Cover set solves the same day, weather day adds another one, backup location replaces the place for the same scenes.
• It only counts as cover if the scenes there are fully prepped: cast called, props on set, lighting plan done.
• Put both versions on the call sheet with a clear decision time, so nobody drives to the wrong address at six.

With TillyGen

TillyGen keeps interior scenes that could serve as cover marked in the plan, so the alternative is picked in advance.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
