Halle Bailey as Ariel in The Little Mermaid (2023)

Halle Bailey's casting as Ariel ignited one of the most heated culture wars in recent Disney history, with #NotMyAriel trending for months before the film's release. The backlash, fueled by the character's traditional white-skinned depiction in the 1989 animated classic, was countered powerfully by viral videos showing young Black girls seeing themselves as a Disney princess for the first time—videos that collectively garnered over 50 million views. Bailey's vocal performance, described by critics as 'angelic' and earning a 95% Rotten Tomatoes audience score, proved decisively more resonant than the casting of Emma Watson as Belle (#4 on this list in terms of controversy), which sparked similar debates but lacked the same emotional cultural payoff.
