Engaging Stone Age animated comedy-adventure follows a cave-dwelling clan whose hominid hover-dad Grug (voiced by Nicolas Cage) is pretty old-school on matters from the family's survival to the boundaries for rebellious daughter Eep (Emma Stone). When an evolved young hunk named Guy (Ryan Reynolds) catches her eye-and tries to warn the Croods of impending ecological disaster-the stage is set for a thrilling journey. With the voices of Catherine Keener, Clark Duke, and Cloris Leachman. 98 min.
