If you look closely and really think what the purpose or reason for these movies is, you’ll realize it is “Who made us?” Searching for our “maker”.
Interstellar and Gravity have one very important thing in common! GRAVITY! In doubt? See the movies!
How do we ever really know WHO OUR MAKER is anyway?!!! Look into your heart and soul!!!!! That’s where the answer is! AND you already know it! Grace is the gift of knowing what is and what isn’t.
