The fourth trailer for Christopher Nolan’s SF movie Interstellar has lifted off.

This is another sci fi film with a grim eco-geddon brewing for Earth, but there’s a new wormhole drive developed by NASA that might save us . . . if only we can find a second Earth out there in time. Let the galactic hunt begin (not helped by FTL relativity meaning time back home is speeding past compared to the astronaut’s desperate efforts).
