Harrelson referred to the pharmaceutical companies as drug cartels who buy off the media and politicians.

"So the movie goes like this," Harrelson said.

"The biggest drug cartels in the world get together and buy up all the media and all the politicians and force all the people in the world to stay locked in their homes, and people can only come out if they take the cartel's drugs and keep taking them over and over," Harrelson elaborated.

"I threw the script away. I mean who's gonna believe that crazy idea."
