Cillian Murphy and Christopher Nolan’s working relationship started nearly 20 years ago when Murphy sought the role of Batman/Bruce Wayne in Nolan’s “Batman Begins.” In a recent interview with Entertainment Weekly, both men admitted to knowing that Murphy was not going to be the new Batman as early as their first conversation together about the role.
