THE ACOLYTE: LUCASFILM IN ADVANCED NEGOTIATIONS WITH AMANDLA STENBERG TO PLAY MYSTERIOUS LEAD CHARACTER: EXCLUSIVE by Caitlin Tyrrell
It has some more interesting tidbits about the nature of the role too. Amandla Stenberg goes by both ‘she’ and ‘they’, is lesbian, and is an outspoken feminist, which sadly means The Acolyte is only going to receive more hate from the usual trolls in this fandom. But fuck em. I’m very glad to learn a little bit more about the series as it’s one of the upcoming projects I’m most intrigued by, and with previous acclaimed roles in movies like The Hunger Games and The Hate U Give, Amandla seems more than capable of trying out Star Wars!
