The new Marvel miniseries “Echo” is one of the first of its kind. The story focuses on a deaf Native American character named Maya Lopez, a.k.a. Echo. Sydney Freeland, the series director, tells Tom about the kind of comic books she read growing up on the Navajo reservation in New Mexico, the challenges of depicting action through the silent perspective of Maya, and how building a relationship with the Choctaw Nation helped bring the story to life.
