Legion may not have been a huge success, but that isn't stopping Syfy and Sony from developing a TV series based on the movie. According to Deadline, Legion's director and co-writer Scott Stewart will be involved in the TV series as a director and executive producer.
Sons of Anarchy writer Vaun Wilmott has signed on to write for the series, which will be produced by Sony Pictures TV. Legion was originally released in January, 2010 and starred Paul Bettany, Dennis Quaid, Lucas Black, Tyrese Gibson, Kate Walsh, and Adrianne Palicki:
"An out-of-the-way diner becomes the unlikely battleground for the survival of the human race. When God loses faith in Mankind, he sends his legion of angels to bring on the Apocalypse. Humanity's only hope lies in a group of strangers trapped in a desert diner and the Archangel Michael."
For those that are interested in this series, keep in mind that it's not a done deal at this point. They are in the process of developing the series, which means that they have to flesh out the concept, get the right cast, and usually film a pilot episode before this becomes a weekly series.
