These are some stills showing the underside of the remote controlled boob.
Anthony Pepe took a mold of a real woman to create this latex version that we could cut into with the doctor’s scalpel. The breast attachtment allowed us to explode the boob off the patients chest as well.

This is a side-by-side comparison of the original 3-d storyboard compared with the final shot. The final shot appears to be one take following the Boob as it avoids attackers running out the door, then we see blood squirting out the door as the doctor has fallen on his own drill saw. The camera needed to go through the wall to achieve this so we actually stiched two shots together to create the continuous effect.

We used the fog machine extensively.

Here are some good shots of the “Boob Cam”, devised by our director of photography, Martin Ahlgren’s, team. It is essentially a practical Boob effect attached to a dolly attached to a camera skimming the surface of the Hospital floor.
We used an 8mm rectilinear lens for the Boob cam shots. It is an amazing wide angle lens that does not distort the image like a traditional fish eye.

This shot shows our production designer Mary Glenn Frederickson with some blood splatter on the wall. There was blood everywhere.

The Boob practical special effects team was lead by Anthony Pepe. He sits on the dolly to closely follow the Boob with his remote controller. This was for the Boob with wheels, which was essentially a remote controlled car with a latex boob on it.
