Earlier last month, Showtime gave a small update on the long-awaited Halo TV series which has been in development for nearly four years. But it looks like the network is finally ready to move forward with the project's production.
According to Production Weekly, filming of Steven Spielberg's Halo miniseries will begin in fall this year. Justin Falvey, Darryl Frank and Alex Maggioni from Amblin Television are attached to the project as producers. So it's safe to say the Ready Player One director is still attached to the project as well.
