No one likes an unexpected visit from their ex after what seemed like a clean break. So when Anne Hathaway shows up on ex-husband Matthew McConaughey’s doorstep to ask him to murder her current husband by throwing him off a boat and into some sharks, it’s like, “I get it, man.” We’ve all been there—that old voice from our past asking us to feed another human to deadly fish. And now we can revisit that familiar sensation with this trailer for Serenity, a film sure to disappoint Firefly revivalists. McConaughey and Hathaway star alongside Jason Clarke, Diane Lane, Djimon Hounsou, and Jeremy Strong. Serenity hits theaters October 19.
