"An actor that does method acting is being hired by the police as a last try to stop a vicious serial killer where the actor is supposed to take on the roll as the killer to be able to find him and put an end to him.?"

I understand. Its not my point to go further with this if someone else work on this.

Warning.

As previously mentioned an idea too similar has already been discussed on this website. It is currently in development with producer attached the concept's various scripts and treatments have been registered with all necessary organizations around the world.

READ BETWEEN THE LINES.

This website is in the public domain but is based on a system of trust and considering the above I trust you understand what I mean.

when his daughter get kidnapped, a grieving method actor takes on the role of serial killer to help the police catch the monster before its to late?

Thanks. Good touch. Ah didn't know that the concept already been discussed here on the site.
:(

Hi Insomniatheater.

This is incredibly similar to a concept has been posted as a logline and discussed on this web site already and is currently heavily in development so just a heads up.

Otherwise the logline is a bit wordy for it's own good.

Nir.

Nice touch, Richiev: personal stakes.
