Behind the Scenes

This is how I created this frightening and crucial scene in my film trailer...

I wanted to give the illusion of a hanging scene, after trying numerous ways to suspend my actress in the air, I decided this way ^^ was most effective and safe.
I rested an exercise bar in the gap of the loft, had my actress climb up the stairs and hang from the bar.
HEALTH AND SAFETY: I made sure someone was standing in the loft to make sure the bar did not slip. Then I used my second actress to observe from the bottom.
With the lights turned off and with my actress slightly swaying forwards and backwards it gave a successful, chilling, "hanging" scene.
