Name that movie...

For a prize, take a guess in the comments. Name the movie and character. Double prize if you can tell me the situation for which the quote arose.

"Roy was hunting stagehands when the Comanches came. I grabbed the baby and a pistol and I hid in the root cellar out back. And the Indians tore up our sod house and I was real quiet but then the baby started crying and I tried to shush him and suckle him but he just wouldn’t stop. One Comanche, I remember, he acted real drunk and he wore my green apron. He must have heard something because he started hollering and coming closer. So I put my hand, gentle like, over my baby’s mouth, “Don’t cry, Daddy’ll be home soon.” The Indians found us but they just laughed, they were drunk. They didn’t want to hurt anybody…just rode away. At sundown Roy came home but I was too afraid to come out of the cellar. I was afraid what he’d do when he saw I smothered our son."

Good Luck!
