AceShowbiz - BAFTA-winning actress Emma Mackey is poised to breathe new life into the role of the White Witch in Netflix's upcoming "Narnia" film. Directed by Greta Gerwig, this latest adaptation promises to tell the enchanting origin story of Narnia as recounted in C.S. Mackey is reuniting with Gerwig, fresh off her recent blockbuster success with the $1.4 billion-grossing, Oscar-winning phenomenon "Barbie". This role was previously brought to life by Tilda Swinton in the 2005 film adaptation of "The Lion, the Witch and the Wardrobe". Joining Emma Mackey's White Witch, Netflix has assembled an enviable cast including the illustrious Meryl Streep, who is currently in talks to lend her voice to the iconic lion Aslan, Narnia's wise and powerful guardian.
