34. Shia LaBeouf
Shia LaBeouf transitioned from Disney child star to serious actor with acclaimed roles in *Transformers*, *Holes*, and the Oscar-nominated *Half Nelson*. By the early 2010s he was a genuine leading man with indie cred and blockbuster appeal, poised for long-term A-list status.
A string of public meltdowns, arrests, and 2020–2021 allegations of emotional and physical abuse from ex-partner FKA Twigs (which he denied in parts but settled) painted him as unstable. Major projects dried up, and Hollywood quietly moved on. The actor once tipped as the next big dramatic force found himself largely sidelined from studio fare.
