Interstellar promises to be one of the most exciting releases of the fall as we head into the holiday and awards seasons. In the latest TV spot for director Christopher Nolan's sci-fi epic, Michael Caine considers both sides of a space mission that may have failed.

It's unclear if Matthew McConaughey's Cooper will ever return to earth after he sets off with a group of explorers who make use of a newly discovered wormhole to surpass the limitations on human space travel and conquer the vast distances involved in an interstellar voyage. His team is looking for new sustainable resources to keep earth from complete extinction. The years tick by back at home, and his children grow into adults as his time in space seems instantaneous.

It's not clear what humanity should be more afraid of. Them ever coming back, or them coming back to find they failed. The end of our world is just the beginning. Just know one thing: Matthew McConaughey is coming back!
