Elizabeth Mitchell and Elizabeth Lail became quick fan favorites as the Snow Queen and Princess Anna during Once Upon a Time's Season 4 Frozen arc. Now the actresses will have a Once reunion as executive producers Eddy Kitsis and Adam Horowitz have recruited them for the new Freeform horror series, Dead of Summer, TVLine reports.

Dead of Summer centers on a seemingly perfect 1980s summer camp, but things aren't what they seem as the getaway turns into a nightmare full of scary secrets and evil. Yeah, definitely no talking snowmen or comedic reindeer to play with in this one.

Mitchell will stay on the dark side as Deb, the new owner of Camp Clearwater whose warm demeanor is a mask for her shady ways. Lail plays Amy, the camp's new counselor who starts figuring out the dark forces at work in the camp. They'll join previously announced cast members including Mark Indelicato (Ugly Betty), Zelda Williams (Teen Wolf), Paulina Singer (Gotham) and Ronen Rubinstein (Orange Is the New Black).

What are your thoughts? Does this sound like a winning cast?
