The idea behind a movie producer making a film remarkable is that people will tell others about it for you. The filmmaker won't have to use marketing as a trick to hoodwink people into watching the film, rather let fans make other fans. Once a movie is remarkable and people see it, they will tell other people and make your marketing easier. Unfortunately, there are other unintended consequences you may encounter that are not so fun.

More Detractors

For every new fan, you'll also make a new enemy. Your online fan message boards that were once friendly and filled with lovers of your work might suddenly become inundated with negative messages from people that don't like you. So while you are spreading the word to fans, you are also spreading it to the indifferent and contrary. You can't please everyone, so it's natural that as your film's profile rises it will attract those that want to tear you down.

More Critics

The more people that see your film, the more likely you will come across would-be critics that find it necessary to pick your film apart in print and put in online. So even if your fans overlook some rough parts of the movie, these critics will bring it to light and might even ridicule you. Even Oscar-winning movies have critics that disagree. No matter how great your film is, somebody will see it differently and try to convince others of their views.

Hunger For More

Just as with any person that makes friends that really like them, these new friends will want to hang out more often. Once your film garners fans, they will want more and more from that storyworld. Though filmmakers often confuse this interest in their story with interest in them as filmmakers, the popularity of franchise movies made by different directors and writers proves it's the story and characters people care about most. There are countless Star Wars books written by different authors and only one of the original movies was directed by George Lucas, yet audiences still stay interested. People care about storyworlds that they like, not so much about filmmakers.

Knockoffs, Parodies

As your film gains in popularity, it's inevitable that someone will made a joke video about it. No movie is spared from this embarrassment and in the USA it's constitutionally protected speech; so there isn't much you can do about it. Whatever is interesting about your film will be used against it to make people laugh. Not only will people want to make fun of you, they'll want to copy what you did. If what you did gets results, people will try to mimic whatever elements they can to ride your coattails to success. Instead of waiting for parodies, you might make your own. Instead of letting others satisfy audience demand for similar productions, you could produce them yourself.

Nobody is going to feel bad for you when these things happen, but all the same they are not pleasant. Fame is a part a movie's success and it has a price. Some of these things can't be helped, but others can be mitigated with some effort. The important thing to understand is that you have no control over others and can only modify your own behavior. Take it in stride and consider it evidence of your work making an impact rather than slights against your person.
