Deutch is the youngest daughter of “Back to the Future” star and TV vet Lea Thompson — Mrs. McFly, get it? — and has a resume that includes a part on Disney’s “The Suite Life on Deck” and guest roles on “NCIS” and “Criminal Minds: Suspect Behavior.”
There’s still no telling how big of a role Juliet, the daughter of Andrew (Ioan Gruffudd) and stepdaughter of Siobhan (Gellar), will play on the series — but in the pilot, her character clearly doesn’t get along that well with her stepmother.
… or, as it were, her stepmother’s twin sister posing as her stepmother.
“Ringer” premieres on the CW, Tuesday, Sept. 13, at 9:00 p.m. ET.
