A possible location...

I have taken some photos of the stage in the auditorium. Whilst it would look unprofessional if we used the stage alone, we think that some clever camera angles, lighting and perhaps the use of green screen would make it look very effective.

This would look unprofessional alone, the tabs (curtains)
will be used just to make the background black.

Lighting will come in very useful.

The floor would be effective as it does not necessarily
look like a stage.
