10 Documentaries About Serial Killers You Should Never Watch at Night


Serial killers engaged our minds like no others. They can be anyone; from the odd-looking guy at the corner of the bar to the cheerful salesman living next door. You will never know until they are in your face with a weapon.

We source out 10 of such documentaries for your viewing pleasure, but you might want to avoid watching them at night in order to ensure a good sleep.

1. Aileen Wuornos: The Selling of a Serial Killer

This documentary follows Aileen Wuornos, who was convicted as a serial killer in 2001. It essentially talks about the exploitation of Wuornos by those around her, including her own lawyer.

It questions the fairness of the trial and explores the vested interest of those around her in convicting her.

2. Aileen: Life and Death of a Serial Killer

This documentary is a follow up to no. 1. It explores the death sentence of Aileen Wuornos and the controversy around it.

Wuornos was pronounced to be “of a sound mind” during her trial but the fact that she claimed that an alien mothership was coming for her one day before her execution said pretty much about her mental state.

3. The Act of Killing

This is not a common documentary as it explores the killing in Indonesia back in 1965 and 1966.

During that time, about 500,000 to one million communists and their sympathisers were murdered by various armed groups done under the encouragement of the Indonesian government.

It features some of the death squad leaders who have personally committed and ordered murder during the purge. In fact, one of them admitted to killing more than 1000 people.

6. H. H. Holmes: America’s First Serial Killer
