Greta Gerwig explains why she cast Meryl Streep as Aslan in her new Narnia movie

Aslan might sound different than you expected in the upcoming Narnia movie. Greta Gerwig recently discussed her adaptation of C.S. Lewis’ fantasy novel The Magician’s Nephew with Empire, explaining why she cast Meryl Streep as Aslan... ... The cover also emphasizes the character’s heterochromatic eyes, which were inspired by David Bowie. Gerwig cites the “Life on Mars” singer and a number of other ’60s and ’70s rock musicians as key creative influences that helped her form the “big and transporting” aesthetic of the film, which she wanted to resemble a “rock opera” despite not being a musical.
