Neil Patrick Harris gets to say his famous catchphrase from "How I Met Your Mother" when he is challenged to a duel by Albert. "Challenge Accepted!" However, according to movie commentary neither of the writers knew this when they were writing the movie and later during test screenings didn't know why audiences were laughing.
The idea of the film was an inside joke by Seth MacFarlane, Alec Sulkin and Wellesley Wild. The three mentioned how the Wild West was always depicted to be dangerous and believed that there are too many ways to die in the setting.
When Anna first meets Foy and Louise at the fair, she moves her hand from Stark's elbow to his shoulder. In the next shot of her, her hand is back where it was before. In the next it's on his shoulder again, where it stays for the rest of the scene.
Anna has her cowgirl hat on with her when she leaves Albert's house. Later when she hides with Edward and Ruth at their place and when she's with Clinch in the town square as a hostage she doesn't have her hat at all with her. It magically reappears right at the end when she & Albert embrace at his house surrounded by the millions of flock of sheep.
