In the HBO documentary “Alive Day Memories” Dawn Halfaker, 27, a former Army first lieutenant, is sitting in a chair on a stark stage, talking, somewhat incongruously, to James Gandolfini, the star of “The Sopranos.”

Mr. Gandolfini serves as the interviewer in the film, set to have its premiere Sunday night at 10:30. It deals with the recovery of American veterans from devastating injuries inflicted during the war in Iraq.

Ms. Halfaker, whose right arm and shoulder are gone, blasted away by a rocket-propelled grenade, says she has wondered whether her child, if she ever has one, will be able truly to love her. And then a look of intense emotion clouds her face. Ms. Halfaker’s eyes flutter, seemingly looking at some image far, far away. Finally, after a long pause, Mr. Gandolfini asks quietly, “What were you just thinking about?”

And Ms. Halfaker tells him: “The reality of, will I be able to raise a kid? I won’t be able to pick up my son or daughter with two arms.”
