Greta Gerwig has released the first trailer for her film adaptation of C.S. Lewis’ “The Magician’s Nephew,” the origin story of Narnia. Across outlets, the preview is described as introducing a modernized, high-concept fantasy—featuring children who discover a magical world and a lion associated with creating Narnia—alongside larger-scale spectacle.

Multiple reports say the film arrives in theaters in February before moving to Netflix in April. Several sources specify an IMAX release for the theatrical run. The trailer also stands out for using Led Zeppelin’s “Stairway to Heaven,” with different outlets noting how the song appears and how Gerwig discusses tying the track to the preview. The coverage also highlights the film’s cast, including David McKenna and Beatrice Campbell, and credits Meryl Streep as Aslan.

While the outlets vary in emphasis—some focusing on Gerwig’s creative approach, others on the trailer’s music or the story beats—they converge on the same central announcement: the first trailer, the Narnia origin premise, and the upcoming theatrical and Netflix release.
