Stagedoor keeper

The ITC, an industry body that represents over 600 members, says:

This role is responsible for making sure the stagedoor is secure, and looking after the keys to the dressing rooms and other parts of the building. They would check staff, actors and visitors in out of the building, will receive deliveries, and will often answer incoming telephone calls.

We’d add to that that the stagedoor keeper is likely to meet and greet performers and fend off eager fans and paparazzi, as well as playing a huge part in the smooth running of the venue dealing with phones, post, fire safety and security cameras.

Stagework says:

Most, but not all theatres have a stagedoor, the place where actors, directors and theatre workers enter the theatre and which is separate from the entrances used by audiences. It is interesting to speculate on why actors and audiences entering the same building should be kept apart from one another in this way. Perhaps it has something to do with protecting the mystique that sometimes surrounds actors, or maybe there is a much more straightforward answer: actors want their privacy respected. The stage door, through which they can pass but their audience cannot, is a helpful tool in ensuring that privacy is maintained, at least whilst they are at work.
