As you may have noticed, in my horror films I often use nudity. Some scenes I've done could be called favorites. Here's a short list of mine.
The above scene, from POV.
The watergun fight from Next Time You'll Know Me.
The walk through an empty apartment while eating from Z-313.
The top of the stairs scene in The Breach.
The lovers on top of each other in A Psychiatrist's Tale.
All of The Last Voice They Hear.
The Polaroid scene in Mr. Billabong.
And the pulling on of a t-shirt in Believe In Monsters.
That's it for me. I'm sure those who've gone the course of several months have your own favorites.
