VIDEO : Tom Hanks and Stephen Colbert Ask Life's Biggest Questions

When was the last time you stopped and just thought about life's biggest questions? Pondered the infinite universe? Asked yourself "What would I do with a time machine?" Stephen Colbert realized that he had a lot to ask life so he went star-gazing with Tom Hanks, naturally, and tackled some of these deeply philosophical topics. For example, "What's the best idea for a movie that's never been made?" Clearly Hanks has the right answer with a film about "an elite team of Secret Service dogs that protect the President's dog," which sounds equally thrilling and moving.
