Your first look at Agent Locke in Ridley Scott's Halo: Nightfall

The first image from the upcoming Ridley Scott-produced Halo: Nightfall was released this week, introducing the new Spartan Agent Locke.

The picture, which was leaked in an accidental post by Variety that has since been taken down, features actor Mike Colter, whose previous work includes roles in The Good Wife and The Following. Colter was previously confirmed as part of the cast; however, while initially the actor was believed to be playing a character called Marlow, sources confirm he's in fact set to play the new Spartan assigned a role in Halo 5: Guardians.

Locke will play "a key role in Halo 5: Guardians," general manager and 343 Industries studio head Bonnie Ross said during a Halo-themed meeting at E3 2014.

"We're using Halo Nightfall to basically tell his backstory and tell his origin story," Ross continued. "You don't have to watch this, but knowing this will kind of tee you up for all the new things that are going on in Halo 5: Guardians."

Los Angeles-based Xbox Entertainment — established to create original content for Xbox One — announced the Halo digital feature last month. Directing is Sergio Mimica-Gezzan, who has directed numerous episodes of Battlestar Galactica, Falling Skies andHeroes, as well as served as Spielberg's assistant director on A.I., Minority Report, Saving Private Ryan and Schindler's List.
