If there's anyone out there who hasn't seen Interstellar yet, let me warn you that the trailer doesn't really tell you anything. If there's anyone who hasn't seen Interstellar or its beautiful yet confusing trailer, let me give you a quick summary.
It's the future. People are farmers (again) and suffering through dust storms and crop blight. Cooper (Matthew McConaughey), one of the farmers, used to be an astronaut. Future NASA recruits him to go on a mission to save humanity along with other scientists/biologists and robots. Their mission is to find another planet suitable for life using a wormhole leading to several possible locations. If one of the worlds can sustain humans, then Earth's population will boogie on over.
Simple enough, right? Well, Cooper also has two kids, who he may never see again since space travel takes a while. As he is traveling, he barely ages compared to them. His daughter, Murphy, who as a child thinks her room is haunted by a benevolent ghost, hates Cooper for leaving. Even so, she grows up to also work for NASA, specifically as a scientist working on the equation that will allow the space station to launch to whatever planet will support human life.
With Cooper saving humans from space and Murphy saving them from Earth, we're in pretty good hands. You'll have to watch the movie to see how it all plays out (and to find out if Cooper and Murphy ever see each other again!). I give this one a solid "Would Watch Again" if only because of its grandness. The soundtrack is as big and as small as each moment requires. I even enjoyed Anne Hathaway's performance, and I'm usually not her biggest fan. Catch this one in theater if you can, or at the very least make sure you have surround sound when you watch at home.
