You're getting confused between upside down and melancholia b/c they both have Kirsten Dunst in it.I'm watching Upside Down now and it doesn't seem to be it. Look , they have the full thing on the tubes. . There's a specific scene with the other planet in the sky and you can at least make out a quarter of the entire planet (it's really close, but not as close as Upside Down.)
Also can we just take a moment to say how stupid Upside Down is. What, they built all their buildings on both sides in the exact same way? Riiiight. Cracked out art student made this film.
