Damnit, beat me to it, haha.
Finally a good trailer which doesn't reveal too much. It reveals why we have to go to space to save ourself and it (THANKFULLY) looks like a good space movie! Definitely has a deeper meaning than just traveling through space since... well, it's Nolan who's directing it (And not Spielberg )
Hmmm ... Looks like a time travel movie to me but that's a sub plot on the face of it, real story seems to be about humanity, the human consciousness and how we view ourselves in the universe. Seems poignant & look forward to it
