A vibrant take on Madeleine L'Engle's classic about two kids traversing the cosmos after their missing dad with the help of a charming friend and a trio of kind souls. Meg: Katie Stuart. Charles Wallace: David Dorfman. Calvin: Gregory Smith. Mrs. Whatsit: Alfre Woodard. Mrs. Which: Kate Nelligan. Mrs. Who: Alison Elliott. Jack Murry: Chris Potter. The Prime Coordinator: Kyle Secor. Directed by John Kent Harrison. Filled with effects and humor, but some scenes may be too intense for preschoolers.
