6. Ezra Miller

Ezra Miller shot to fame as the quirky Flash in the DC Extended Universe, with *Fantastic Beasts* roles and *The Flash* solo film (2023) positioning them as the next big franchise anchor. Their eccentric charm and talent had studios excited.
A string of 2022 scandals—including arrests for assault, burglary, and disorderly conduct, plus public accusations of grooming and emotional abuse—derailed everything. Miller issued apologies and entered treatment, but *The Flash* flopped, and Warner Bros. shelved future plans. No major projects have followed. The promising young star’s Hollywood future remains uncertain at best.
