How big does the conspiracy go? Uncover the truth behind the CIA, LSD, mind control, and the death of a family man in the first trailer for Netflix's Wormwood, a six-part miniseries from director Errol Morris. The series will also be released in select theaters while also debuting on Netflix on December 15, with this project hitting the film festival circuit earlier this year, debuting at the Venice Film Festival in September and screening at AFI Fest last month.

Directed by boundary-breaking filmmaker Errol Morris, Wormwood explores the limits of knowledge about the past and the lengths we'll go in our search for the truth. A twisting, evolving story of one man's sixty-year quest to identify the circumstances of his father's mysterious death. Combining a virtuosic performance by Peter Sarsgaard with Morris' legendary interview style, Wormwood examines this case from every possible angle, bringing the viewer face-to-face with some of the United States' darkest secrets. Wormwood sets a new standard for nonfiction filmmaking and finds Morris working on his grandest canvas yet.

This miniseries combines both documentary and narrative techniques, with Peter Sarsgaard starring as Frank Olson in these narrative re-creations, an Army scientist who, according to his son Eric Olson in new interview segments, had a working relationship with the CIA. The CIA reportedly took Frank Olson to New York City on Tuesday, and he was dead on Saturday, after plunging to his death after jumping out of a hotel window. Frank Olson was part of the CIA's program known as MK-Ultra, where the spy agency used LSD on patients for mind control experiments, and over the years, evidence mounted that suggested Frank Olson's death was not in fact an 'accident,' but may have in fact been a murder.

Also starring in the narrative reenactments are Tim Blake Nelson, Molly Parker, Jack O'Connell, Scott Shepherd, Jimmi Simpson, John Doman, Michael Chernus, Christian Carmago and Bob Balaban, although no details about their characters have been given. Errol Morris directs this six-part series from a script by Steven Hathaway and Molly Rokosz. Sean Fogel, Steven Hathaway and Julie Bilson Ahlberg serve as producers, while Adam Del Deo, Peter Friedlander, Lisa Nishimura, Errol Morris, Robert Fernandez and Caroline Baron serve as executive producers.

This six-part series will likely only get a limited theatrical release, much like how ABC's Inhumans opened in select IMAX theaters before debuting on ABC. It will be arriving on the same date that Disney's Star Wars: The Force Awakens and 20th Century Fox's Ferdinand hits theaters. Take a look at the new trailer and poster for this new Netflix series.
