Speaking to Entertainment Weekly, Mangold confirmed that the story is based on the comic arc by Chris Claremont and Frank Miller.
"A lot of that story and a lot of beats from that saga are in there, and a lot of characters," Mangold revealed. "Without being religious about it, I think it's a very admiring adaptation."
Mangold went on to expand on Logan's (Hugh Jackman) arc in the film, which takes place after X-Men 3: The Last Stand, confirming that he spends much of the story isolated.
"I felt it was really important to find Logan at a moment where he was stripped clean of his duties to the X-Men, his other allegiances, and even stripped clean of his own sense of purpose.
"I was fascinated with the idea of portraying Logan as a ronin - the definition of which is a samurai without a master, without a purpose. Kind of a soldier who is cut loose.
"War is over. What does he do? What does he face? What does he believe anymore? Who are his friends? What is his reason for being here anymore? I think those questions are especially interesting when you're dealing with a character who is essentially immortal."
It was recently confirmed that Jackman will appear in X-Men: Days of Future Past, Bryan Singer's upcoming sequel to X-Men: First Class.
