Barbie and Little Women director Greta Gerwig is tackling C.S. Lewis' Chronicles of Narnia saga for Netflix, with a 2027 release on streaming and in IMAX theaters. On Monday, Netflix released a new look at Gerwig's Narnia: The Magician's Nephew in the form of a striking poster. The better news is that fantasy fans will get an honest-to-goodness sneak peek at the movie on Tuesday, when the first trailer for Narnia: The Magician's Nephew is slated to drop.
