AMC has added one more person who’ll Fear the Walking Dead: 666 Park Avenue actress Mercedes Mason.

Like the forthcoming series’ already announced castings, not much is known about Mason’s character. Our sister site Deadline, which broke the news, reports that Ruben Blades is in negotiations to play her alter ego’s dad.
