You should rent it sometime (the original--haven't seen the remake but hear it's not as good).
As I was noting in another thread, I think it more effective to juxtapose pictures of live fetuses with something like the pictures of jars, without showing the mangled fetuses. The problem with the latter is that it will tend to direct the viewer's revultion toward the [mangled] fetus, rather than at the act of mangling the fetus.
And what will be the outcome of the viewer's revulsion?
Imagine you are walking along a street and you see a man knifing a small child who is in a group of small children. You happen to have a Swiss Army knife.
Do you refrain from using it to stop the man, because the other children might be shocked by what they will see?
Do you use the means at your disposal to stop the killing?
