Serenity (2005)

River Tam is brilliant, awkward, and the most wanted object in the 'verse. Along with her brother Simon and a crew of lovable misfits, River is hanging out on the edges of space, trying to avoid the authoritative Alliance. Unfortunately for the crew, River is even more valuable than anyone realizes, and the Alliance will stop at nothing to get her back under their control. Is space large enough to hide one small ship or will River and the crew of the Firefly end up in an Alliance jail -- or graveyard?

Serenity is an action movie featuring Nathan Fillion.
