Upside Down is a new project from Argentinian filmmaker Juan Diego Solanas that is being described as “an alternate reality and groundbreaking” sci-fi film.

According to Production Weekly, Solanas has just cast Jim Sturgess and Kirsten Dunst, to star in this project.

Here’s the best description of the concept from the European Film Market brochure (via /Film)

Look up towards the sky and rub your eyes because you won’t believe what you see: cities, forests, and oceans with their own inverted gravity, only an arm’s length away, yet completely unreachable. Take a leap over to this alternate reality, two worlds – one above, one below – facing each other, and you’ll land in the extraordinary world of Upside Down, the new ground-breaking film of Juan Solanas.

Adam is a seemingly ordinary guy in a very extraordinary universe. He lives humbly trying to make ends meet, but his romantic spirit holds on to the memory of a girl he met once upon a time from another world, an inverted affluent world with its own gravity, directly above but beyond reach… a girl named Eve. Their childhood flirtation becomes an impossible love. But when he catches a glimpse of grown-up Eve on television, nothing will get in the way of getting her back… Not even the law or science!
