"Echo," set to premiere on January 10, marks several firsts for Marvel. It will be the first Marvel production to debut simultaneously on Disney+ and Hulu, the first to be available for binge-watching, and the first to carry a TV-MA rating. Director and executive producer Sydney Freeland highlights the importance of representation as the series centers around Maya Lopez (Alaqua Cox), Marvel's groundbreaking superhero series featuring a deaf and Native American character.
