Sure, there are other factors at work. But my point is - how do you make your content stand out? How do you make your film stand out?
Before, films and content was like a small trawler net full of a lot of rock, with a few gems and a couple diamonds.
Now, you've got a huge trawler net full of rocks, gems, diamonds and everything in between. So how do you make your gem, or your diamond, or even your rock, stand out from the rest of them? Why should people invest in, or go see your Ruby when someone has an Emerald over here that's just as attractive?
If this is being asked in the way I think it is, then I feel that it is a bit misguided.
To ask this question means to ask "what should I do to make people like me just as much as they like this other artist?" Which can translate to, "what elements must I borrow from these other more profitable and well-received films to make mine attract the same attention."
I'm not exactly saying that this is the only interpretation of that question, but it's the most obvious.
Basically what I'm getting at is that if you feel that you must borrow the spark from another film to bolster your own, then you are simply falling back into the same trap as many Hollywood producers and executives do when they want to ride the gravy train that a stand-out movie managed to start up. And so you begin to see a lot of copycats and imitators copying the look, the mood, the style, the atmosphere, the stylistic elements of costuming, setting, music, or artwork, etc. Until eventually the market is just saturated with stuff that is nothing but a mere shadow of what originally became the most popular. Somewhere in there you may get a film that is similar in aesthetic but different enough that it becomes its own thing, but the reason that this imitator becomes an original and likable concept unto itself is not because it does what is popular, it usually does so because its filmmakers have a particular gift and a unique voice to share that stands above the imitated qualities.
Therefore, I feel the real question you should be asking is, "what do I have to offer that is just as valuable as this other filmmaker?" "What stories do I enjoy, what images do I like to photograph, and what emotions do I like to conjure up that will make audiences appreciate the experience just as much as other popular films?"
You must develop your own style and your own vision. One should never build a film a career out of only doing what is popular or profitable, except when doing so is required to reach the next step where you hopefully will not have to.
If you yourself have something to offer (stylistic camera work, cinematography, unique production design, you specialize in a particular genre or type of stories, etc.), then that is what producers, investors, and audiences will gravitate to. If you don't have something which other people like that is inherent within your current or future developing skills and interests (as well as influences), then I daresay maybe you just aren't cut out for filmmaking. No one can stop you from still pursuing it. But then if all you do is chase the money or the fame with no regard for what makes you most happy, then you may find yourself in a very dispassionate career with very little to show for who and what you are as an individual artist.
Again, this is an extreme case. I simply wanted to fully express where I feel this mode of thinking can lead to. And I have a feeling that Cracker Funk will agree. The whole point of his topic here is to get people excited about changing the face of filmmaking and forging a new path for visual storytellers. And so you must cultivate your own original voice as much as you can.
Also, just in case someone tries to take what I say here as "ALL" I believe in: no, I am not saying that one should and can only ever do stuff that appeals to them, lest they lose their artistic originality to the corporate marketing machine.
On the contrary, I think while it is important to develop and cultivate ones own directing style, the projects one does and the stories one tells may often need to be somewhat impersonal yet profitable jobs that will have a bigger chance of getting you noticed than something entirely all your own ever would. You have to climb that ladder to success somehow, and many times it will involve taking opportunities when and where they come and pushing through the jobs you don't like to get the next opportunity that may allow you to work on a project that you do like.
And like AudioPostExpert said, it is highly advisable to not only take "calculated" risks when the timing is right, and forge a unique path for yourself that makes you stand out, but to also maximize your potential by being well-prepared and doing things (sometimes only small things) that will increase your chances of being noticed and recognized for your talents and your films.
P.S.
One of my biggest dreams is to direct adaptations of some of my favorite cartoons and video-games. So I am also not saying that one cannot become the director of some existing property. Whether you personally enjoy that IP or not, directing an adaptation is perhaps one of the best chances you have of reaching a better level in your filmmaking career, and should not be seen as something that diminishes your artistic integrity. On the contrary, it is your own filmmaking style that will add that new spark of life into such an existing property. Okay, maybe not for Uwe Boll; but definitely for J.J. Abrams, Christopher Nolan, Tim Burton, and Peter Jackson, just to name a few.
