A young couple become intruders in their own home after they discover it’s being shared by a couple who look exactly like them.
A story premised on the predicament of the double or doppelganger is rich in dramatic possibilities. Which is why there is already a number of films based on that premise. One of the most famous is Hitchcock’s “Vertigo” and the one that came to mind when I read this logline was “The Double”, the 2013 adaptation of Dostoevsky’s novella.
And, hey, any idea worthy of treatment by Fyodor Dostoevsky and Alfred Hitchock is certainly worth another go around. But what would distinguish this effort from theirs and all the other treatments? What’s the hook, the unique twist?
In “The Double”, the hook, the running gag, is that the personality of the doppelganger is the polar opposite of the protagonist. Unlike the protagonist, the double has the extroverted charisma to impress the boss, get promoted and also score with the girls. (A similar gag Charlie Kaufman played around with his identical twins in “Adaptation”)
So, given that the predicament of the dual protagonist in your concept, kbfilmworks, what is the hook, the running gag? What becomes their goal? What MUST they do about the situation they find themselves in?
I have no idea where you are going with the story and, of course, you don’t want to give away the ending, but one possibility that came to my mind is that protagonist couple have kids — and the doppelganger couple are so much more appealing and better parents. Hence, the kids want to dump their real parents for the doppelganger couple. So the stakes would be greater than just winning back their residence; they must win back the hearts and minds of their kids. (Echoing the predicament of the protagonist in the new film “Daddy’s Home”, I know, but it’s an enduring, perhaps archetypal, conflict.)
Anyway, as I said, it’s a premise rich in dramatic possibilities. But I suggest the logline needs a little more specifics in order, to differentiate the story you want to tell from that of all the other double/doppelganger films already out there.
Thanks for your insightful comments. I think the genre differentiates it. It’s Science Fiction along the lines of ‘Primer’ and ‘Coherence’ and the logline is for a short film. So, it’s basically setup and climax. The climax is a ‘Twilight Zone’ style payoff that resolves the mystery of the doubles. So, I can only include the setup in the logline.
