Amanda Seyfried has said working on Seth MacFarlane's Western comedy is a hilarious experience.
The Les Miserables actress told MTV News she and her co-stars in A Million Ways To Die In The West were having a tough time not cracking up over every line in the script.
She said: "Everybody's laughing all the time. It's like nobody cares about the fact that they've been shooting a 14-hour day. Every line is hilarious."
Amanda stars alongside Charlize Theron, Liam Neeson and Sarah Silverman in the comedy about a cowardly farmer who enlists the help of a gunslinger's wife to help him win back the woman who left him.
Seth also stars in the film, as the farmer trying to get his lost love back.
Amanda said of Seth: "It's amazing, he looks like a movie star. He's very focused on what he needs to do and he watches the takes, but then all of a sudden he's next to you in the scene, and you're like, 'Uh, are you watching what I'm doing, or...?' And then he yells cut when he's in the scene."
A Million Ways To Die In The West is currently filming and is due out in May 2014.
