Best Zero Gravity Movie Scenes In Honor Of 'Upside Down'

"Upside Down," the sci-fi romance opening in theaters this week, casts Kirsten Dunst and Jim Sturgess as star-crossed lovers separated by a slight difference in gravitational pull. Each lover's world pulls him or her in opposite directions from the other, so when they attempt to cross over and be together, it makes for some fun gravity effects.

In honor of the release of "Upside Down," we've compiled some of the most classic moments of zero gravity effects from the movies. Check out our list below!


"Matrix Revolutions"

"Royal Wedding"


"2001: A Space Odyssey "

"Apollo 13"

"Dancing on the Ceiling"
