I used to know a girl who could speak backwards fluently. It was cool, but not really helpful to anyone and certainly unintelligible to anybody who couldn’t also speak backwards. Far more useful is the ability to speak only in film titles, which the couple in this short film manage to do reasonably well over the course of their break-up at a restaurant.
It’s a great little short film. The script must have taken weeks to get together, but it all comes together quite well. You almost don’t notice that people don’t really talk like that at all.
