The stage play is a trial, not a deed of violence. The soul is opened, like the combination of a safe, by means of a word. You don't require an acetylene torch.
One of the issues peculiar to community theater is dealing with inexperienced or outright bad actors who are so unimaginative, so lacking in energy, that no matter what devices you use, you just don't seem to be helping them that much. They will improve. It is your rseponsibility that the actor should ever feel that he or she has failed.
In comedy, beware the split focus. The audience should focus on the face of the actor. The audience must see the setup. If there is action elsewhere on the stage, the comic line can be lost.
Don't let a single comic moment pass you by; then help the audience get the laughs. Give them permission to laugh by holding for laughter and by letting them know early on what they're in for. In the first few moments, the audience is gathering information, looking at the scenery and costumes. Create a comic moment as soon as you can.
Most directors work from inside out and from the outside in. They concentrate not only on the life of the characters but also on the play's structrual or external elements, including its central conflict, function, event, architecture, and suspense.
