Fx turns too real? 

 

In the 1980's there was a little shocker we like to call Cannibal Holocaust. This was not necessarilly a good movie but it was one with many shockers and many gorey fx. This FX for one landed them on trial for murder. 

 

The authorities actually charged them with 

skewering a woman to get this effect.

They had to go through and prove that the 

woman is actually sitting on a bicycle seat

and she is alive and well.
