Here’s the latest trailer for Christopher Nolan’s global warming/space travel epic Interstellar, now reported to clock in at a you-better-deliver 175 minutes. Where the last trailer had Michael Caine orating Dylan Thomas to urge humanity to not go gentle into that good night, this time the exposition gives a more concrete idea of what to expect, which may or may not be a good thing depending on your tastes. There’s also lots of Matthew McConaughey urging people not to give up and what appears to be the biggest tidal wave since The Abyss‘ director’s cut.
