"Different " Camera Angles
Here's a few ideas for some creative ways of showing things -
Reflections
-Have a water puddle with the reflection of your actor walking by
-Shoot through a mirror, then zoom out in the scene, catching the viewer off-guard. This is done very well in the movie Ghost.
Play with Lighting
-Shoot in silhouetes, which always give a more mature mysterious feeling to your character, and also may allow some sexuality in your film without fully exposing the artists and keeping your rating a bit more viewable.
