Despite all the scenes of death and violence, the ITC received five complaints from viewers concerning a scene where a frog is apparently liquidized in a blender. The ITC did not uphold the complaint.
The head-shots in Dollhouse Burns 1 & 2 were an effect that was originally conceived for Saving Private Ryan. A tiny pyrotechnic is attached to a specially machined aluminum plate that sits on the actors forehead. This is then hidden underneath a prosthetic appliance made from gelatin. The prosthetic has a hole already cut out where the bullet hit will be which is then disguised with a soft wax material that now makes the forehead look natural. A blood tube and firing lines for the pyrotechnic are hidden in the performer's hair and then on cue the charge is detonated. Although only weak the tiny charge easily punches a hole in the wax and blood begins to flow.
Boyo's severed head in the episode "Eater" was produced by first taking a cast of actor Glyn Morgan's own features and then reproducing this in wax. This was then worked on sculpturally to create the torn flesh look of the neck. The wax copy was then molded in fiberglass giving a negative mold from which a skin of silicone was then produced. This skin was then painted using reference photos of Glyn. Eyes for the head were hand-painted to match Glyn's from photographs of his eyes and inserted into the silicone head. The final step was the hair. To make the hair look as if it is growing from the head each hair has to be inserted into the silicone skin with a special needle one by one. The process took almost three days. Even the eyebrows and eyelashes had to be inserted individually to complete the effect.
