Those who watch “Harmontown,” the Neil Berkeley documentary on controversial “Community” creator Dan Harmon, certainly learn a lot about the showrunner — but it ultimately may have been Harmon himself who learned the most from the film.

Harmon and Berkeley talked about the documentary, which follows Harmon as he tours the country with his podcast after being fired from “Community” in 2012, at a screening and Q&A at the WGA Theater in Beverly Hills Wednesday night. Harmon noted that the documentary focused on plenty of his low points — including drinking moonshine on stage and getting in fights with his then-girlfriend, now fiancé, podcaster Erin McGathy.

“You don’t see me rise back up in that movie,” said Harmon. “You see me realize that I’m a big baby and you see me realize that I can’t be a man.”

According to the “Community” creator, seeing himself interact with his girlfriend on screen made understand how “clinically mean” he was to her.

“I had to have a documentary made about me to see that what a shitty boyfriend I was,” he said. “I’m not kidding at all. You can see me behaving that way toward her.”

Harmon looking good, though, was never the point of the documentary. Harmon he reached out to Berkeley, best known for 2012 Wayne White documentary “Beauty is Embarrassing,” in part because he “would rather be a bad person in a good movie than a good person in a bad movie.”

Harmon admitted that if he looked too good, the movie would be a farce. Despite the fact that Harmon’s a producer on the movie, Berkeley pointed out that Harmon’s notes on the movie were not about the writer’s image.

“You never said, ‘I look bad there,’ or ‘I look too good there,’” said Berkeley. “There were notes about structure: ‘If you move this here, it’ll feel better, the pacing will be better, this storyline will be better.’”

The two revealed that, when Harmon was first talking to Berkeley, he had originally pitched a mockumentary of sorts — a “silly tour movie,” said Harmon, rather than the in-depth look at his character that “Harmontown” came out to be.

While Berkeley was fine with that at first, after further thought, he couldn’t go down that road.

“He was saying, ‘I can’t do that,'” Harmon recalled. “I can’t do that mockumentary thing. I can’t do this engineered thing.’ And I was like, ‘Wait, what do you want? Just say what you want, man. I’ll do anything!’ At that point, we had to do a handshake deal: It was my tour, and his movie.”

Those who have seen both of Berkeley’s “Harmontown” and “Beauty is Embarrassing” may notice similarities in the documentaries’ central subjects, which the director acknowledged. In fact, pointed to that as a draw to do the Harmon doc.

“I’m incredibly and attracted by people who do whatever their minds and bodies do everyday, regardless of the consequences and I think Dan and Wayne have that in common, very much so,” he said.

“Harmontown” will be released by The Orchard on Oct. 3 in LA and VOD and Oct. 10 in New York City.
