Tribeca Film Review: ‘The Leader’ is an Unsettling Look at the Heaven’s Gate Cult with Captivating Performances from Tim Blake Nelson, Vera Farmiga, and Jim Parsons

Cults fascinate us. That goes without saying. Hell, sometimes the fascination can lead to indoctrination. In the case of the “Heaven’s Gate” cult, which it’s no spoiler to say ultimately turned into a suicide cult, what the group stood for was ludicrous. So, it was the charisma of the leader in charge that sold that particular bill of goods. The Leader drills down on this, as the film is far more about the lost souls who came together, as opposed to just the ultimate tragedy. Playing at the 2026 Tribeca Festival, the people at the front of the cult take center stage, resulting in a compelling and even occasionally offbeat work.

The Leader has moments of oddness that help give it a distinct flavor, even as the narrative itself is presented in a fairly straightforward manner. Those familiar with the UFO cult are unlikely to learn too much about the organization that they didn’t already know, but they will likely end up with a greater understanding of the people within it. At the same time, if this is something you know nothing about, prepare to have your mind blown.

As we’re told right off the bat, in 1997 thirty-nine members of the “Heaven’s Gate cult committed what would be the largest ever mass suicide on American soil. We then find out their story, told through their founder, as well as some members. When Marshall “Herff” Applewhite (Tim Blake Nelson) meets Bonnie Lu Nettles (Vera Farmiga) in the 1970s, both were searching for more in their lives. The latter was an unhappily married wife and mother, working as a nurse, where one of her patients is the former. He’s clearly got mental issues, but he’s also charming and charismatic, leading to an instant connection. Their bond would lead to the creation of their organization, centered around a belief that the human body was merely a container for the soul, eventually growing to become home to almost two dozen members.

Amongst their believers is Warren (Jim Parsons) who rigidly adheres to their dogma as a way of controlling his demons, as well as others like Michelle (Grace Caroline Currey) and David (Simon Rex). As we watch Warren’s struggles, as well as his determined belief in Herff’s teachings, we also see how people like David and Michelle might struggle. When Bonnie gets some troubling news, it shakes Herff, setting everyone off on a course that would lead to the mass suicide that ultimately captured the attention of the nation.

Tim Blake Nelson, Vera Farmiga, and Jim Parsons are each very good here, with Farmiga and Nelson captivating. Nelson is the perfect actor to play this man, leaning into both his charisma as well as his massive self doubt. You’re always compelled by his words, even if you know they’re ludicrous. It’s one of his best performances to date, which is saying something. Farmiga is also excellent, pulling no punches as the matter of fact Bonnie. Together, they truly are a formidable match. The big surprise is Parsons, who was hilarious for years on The Big Bang Theory, but here plays a straight dramatic role that asks a lot of him, which he delivers. Ultimately, he’s the character you end up feeling the most for by the time the credits roll. Grace Caroline Currey and Simon Rex are very solid as well, though they’re far more supporting in nature. The cast also includes Kaitlyn Kemp, William Mapother, Don McManus, Kelly Lynn Reiter, Danielle Vasinova, and more.

Filmmaker Michael J. Gallagher is clearly fascinated by cult leaders, which imbues both his writing and directing here. There aren’t any flashy visuals, though a few editing tricks are fun to help keep things lively, as are the occasional moment of dark humor. The main hiccup is some slack pacing, though it’s not a crippling issue. Gallagher’s casting choices pay real dividends, however, and that’s the movie’s biggest success. The writer/director never shies away from how unsettling this all is, but he’s more concerned with the humanity behind it all.

The Leader could have stood to have been a bit tighter, though at 104 minutes, it’s hardly too long of a flick. There’s just a few sections that drag, even though the cast always hooks you back in. This is likely to be one of the higher profile Tribeca titles this year, without question, and it’s also likely to end up as one of the better ones, too.

SCORE: ★★★
