Film is a business unlike many others: You can write a book on your own, you can make art on your own, and you can compose music on your own, but film will always be a team effort. Yes, you likely need a visionary person to kickstart the film. This is typically the director, producer, or writer, but you will also need help from hundreds of other people along the way, whether they're your subjects, actors, financiers, assistants, musicians, interns, and dozens upon dozens more.
Working on a film is like being in the army: you'll likely become super close with many of your colleagues, pulling late nights, early mornings, and spending hours in the freezing cold or blistering sun. And you'll love these people.
However, film also draws its fair share of horrible, really bad, disgusting, worst-of-the-worst people. These people take on different forms:
1. Narcissists are the worst. If you've ever met one, and I'm sure you have, you know. It is unfortunate when narcissists make films, but quite frequently, they do. (I won't name names, but in this industry, it is generally known...) Many narcissists are drawn to film for the fame and/or fortune but don't want to do any of the hard work to get there.
2. Hustlers are another breed with little/no talent who somehow never make projects but are always raising big money for something. They're annoying because they take money away from people who really do need it and will do good with it. And they also give a bad reputation to filmmakers when they raise money and make flops. Understandably, it is hard to differentiate between a hustler and a legitimate producer, as when anyone starts off they could fall into any category. It is necessary to hustle in your early years. But as people age, you start to see who's peddling nonsense and who's legit. But after many years, if someone gets nothing concrete done, you can assume they're a hustler not a filmmaker.
3. Film likely also draws a disproportionate amount of "rich kids" into its mix, because, by the time you're 25, 30, or older, if you aren't independently wealthy, film isn't going to be a profession that you're going to be able to afford to partake in, because it requires a ton of time, much of it unpaid, before payouts come at the end of some very long and challenging roads. A lot of rich kids float around, call themselves filmmakers, do a ton of cocaine, and hang out with B, C , or D list celebrities but have 0 talent or ability to execute. (It is necessary to write that there are some rich kids out there who do make amazing films and are generous with both their time and money. I know a handful of them who are genuinely talented, hardworking, and good people and they are very important people in my life!)
4. Then there are the struggling filmmakers, who are really just lazy folks who never wanted to get a job and like to sleep late, not work much, and be generally lazy SOBs. There are a lot of folks like this running around East London (where I now reside) and Brooklyn (where I formerly resided). You'll likely see them sipping coffees or asking you for meetings and then show up at said meetings without ideas that are thought through.
5. Interns who think they are god. This is another sad, sad breed of young humans. I've encountered plenty of amazing interns in my day (who have been lifesavers) but just as many cocky, arrogant, bad people who will likely wind up in category 3 or 4 above. In many ways, my biggest lesson is not to hire interns from good schools. I went to the University of Oxford and the University of Pennsylvania, and have hired gems from both places, but I've also had my fair share of arrogant/lazy folks from each institution.
The real message here is you must work with passionate people who work hard. Unfortunately, the world is saturated with people, perhaps over 80% of them in film, who really are useless and suck. You must fire these people quickly and only keep the talented people who have good work ethics and strong morals around. Otherwise, your life will become hell, and you won't be making movies, you'll just be miserable. I didn't let this happen to me, but if I didn't fire fast, it easily could have happened.
