So filmmakers lie to actors and actresses all the time. I got it. No need for you and I to go back and forth your argumentative tactics are not sufficient to continue this debate further.
You keep missing the point, let me spell it out for you.
Your OP argued that the film is shameful because the the producer lied to the actors. Unless you are going to argue that all films made by producers that lie to actors are shameful, a position you clearly do not hold, which would be absurd even if you did hold it, your OP makes no sense at all.
My advice still stands, find a real reason to call the film shameful. The fact that the producer is beneath contempt does not make the film shameful, it makes the producer shameful.
You don't need to spell it out for me because I don't respond to strawman. Your assuming that every film involves deception and I do not think that is the case. Actors like Tom Cruise, Morgan Freeman, Halley Berry, Denzel Washington and award winning actors are not deceived. If they were do you not realize that many of these actors would sue or choose to not do movies. So your assertion that deception is a common thing (such as actors knowingly having their voices dubbed over with a voice not of their own) is a moot point. the film is shameful as I previously mentioned, and not only because its shameful due to his poor attempt at excersing his first amendment right, but shameful because he had to deceive many to do so.
If the logical reasons I have provided in the above doesn't satisfy you perhaps a list will:
1) The film was made in poor taste. If you're trying to convey a strong message the film needs to be logical, coherent, and consistent.
2) The actors didn't know the true intent of the movie aside from what they were told.
3) The writer Basile, went to jail for fraud, therefore his credibility as a person is in question.
4) Upon pre-screening there was only 10 people that watched it.
These are the main reasons as to why I find the film shameful. If any writer is trying to convey a message from his own idea, then its imperative that those ideas are clearly made which in this case it wasn't.
