"Silver lining" actress, Jennifer Lopez, is set to make her directorial debut with the movie "Project Delirium," a film on US military experiments in mind-altering chemical weapons.

Speaking to Entertainment Weekly about the project, the actress said; I have wanted to direct as long as I’ve wanted to act. I just don’t talk about it because I’d rather just do it. I’ve signed on to direct something called ‘Project Delirium."

it’s based on this article about mental warfare in the ’60s, like an acid experiment gone terribly wrong. It’s funny, I’ve wanted to direct since I was 16 and always thought I should start making steps towards that. If I had tried to do it earlier, I wouldn’t have been ready. Now I actually feel ready.”

"Project Delirium" will tell the story of research carried out by Colonel James S Ketchum, who tested psychoactive chemicals on around 2,500 soldiers in the belief that such agents could be used to incapacitate enemies.

The star won an Oscar in 2013 for starring in "Silver Linings Playbook" alongside Bradley Cooper.
