Traveling to another planet is the ultimate long-distance flight. And just like any long-distance flight, you need some entertainment. What better way to kill time while hurtling through space in Richard Branson’s Virgin Galactic shuttle than by marathon back-to-back screenings of Christopher Nolan’s space-travel epic, Interstellar? The 169-minute movie is the ideal in-flight entertainment. Even if it means watching it 8,000 times.
