File this firmly in the rumor category, but according to Twitter user DanielRPK - who has been on point with DC movie info in the past - Andi Mack actress Peyton Elizabeth Lee might be a contender for the role of Cassandra Cain in Birds of Prey.
Warner Bros. and director Cathy Yan are said to be casting a very wide net to cast this role, so even if Lee is one of the young actresses that has read for the part, she most likely has a lot of competition.
