The procedural matters were scheduled for Tuesday with openings expected Wednesday in the trial of Eddie Ray Routh, a former Marine charged with capital murder in the deaths of Chris Kyle and Kyle's friend, Chad Littlefield. They were fatally shot at a gun range in 2013.

A jury of 10 women and two men was seated Monday.

The movie is based on Kyle's memoir. The celebrated sniper served four tours in Iraq.

Routh's attorneys plan to pursue an insanity defense. Prosecutors aren't seeking the death penalty. Routh faces life in prison without parole if convicted.
