Mom & Dad [Blu-ray/DVD]

A strange disorder suddenly causes parents to violently turn against their own children, forcing a suburban teen (Anne Winters) and her younger brother (Zackary Arthur) to evade the clutches of their now-deranged mom (Selma Blair) and dad (Nicolas Cage). However, their situation gets even more complicated when their grandparents (Lance Henriksen and Marilyn Dodds Frank) show up for a visit. Written and directed by Brian Taylor (Crank, Gamer).
