Syfy has announced that it will be greenlighting "12 Monkeys," a drama series based on the 1995 Universal Pictures film directed by Terry Gilliam, to pilot. The 60-minute cast-contingent pilot is being produced by Universal Cable Productions and Atlas Entertainment, producer of the original Bruce Willis-Brad Pitt theatrical.
Based on the Gilliam film (in turn inspired by Chris Marker's 1962 short, "La Jetée," "12 Monkeys" follows the journey of a time traveler from the post-apocalyptic future who appears in present day on a mission to locate and eradicate the source of a deadly plague that will eventually decimate the human race.

The premise of the movie seems a bit limting to be made into a series. Would this just be "Seven Days" in a space suit?
