With it's summer premiere date fast approaching, AMC's "Walking Dead" spinoff "Fear the Walking Dead" has started to round out its cast. As revealed by Entertainment Weekly, actress Elizabeth Rodriguez has joined the show in an unrevealed role. The site speculates that, since the series' pilot episode has already been shot, it's likely that Rodriguez's mystery character will appear on the series at some point after its initial episode.

Fans of Netflix's runaway dramedy hit "Orange is the New Black" will be familiar with Rodriguez; the actress portrays Aleida Diaz on the series, mother of Daya. The third season of the series arrives on the streaming service on June 12. This won't be the first time that Rodriguez has pulled double duty on simultaneously airing TV shows; the actress had an arc last year on "Grimm" as Agent Chavez in-between "Orange" seasons.

Set in Los Angeles prior to the massive zombie outbreak featured in "The Walking Dead," the spinoff series will star Cliff Curtis as divorced teacher Sean Cabrera and Kim Dickens as the female lead, a guidance counselor named Nancy. Frank Dillane and Alycia Debnam Carey are also attached to star as Dickens' children, Nick and Ashley.

Adam Davidson, who previously helmed episodes of "Friday Night Lights" and "Fringe," directed the recently-wrapped pilot. The companion series will be executive produced by "The Walking Dead's" Kirkman, Dave Erickson, Gale Anne Hurd and David Alpert. "Fear the Walking Dead" has already received a two-season commitment from AMC; the first six episodes will debut this summer with a second season following in 2016.
