The Belfast Telegraph (spotted by VG247) has details on the Halo project being shot currently in Belfast's Titanic Quarter, which will form the basis of a digital feature due for later this year.
As the newspaper points out, Scott is producing, with Battlestar Galactica's Sergio Mimica-Gezzan on directing duties.
It's part of Microsoft's heavier push into the TV market, with a spokesperson confirming to the outlet that "343 Industries, Xbox Entertainment Studios and Scott Free Productions are currently working on a Halo digital feature project to be released later this year".
While the production is closely guarded - we've been trying to get access this past week from sources on site - some filming is taking place in public areas. The Telegraph piece also includes some scenes shot around the docks, and captured on mobile by a passer-by.
