25. Katherine Heigl
Katherine Heigl was Hollywood’s rom-com queen after stealing *Grey’s Anatomy* and delivering hits like *Knocked Up* and *27 Dresses*. By the late 2000s she was commanding top billing and multimillion-dollar paychecks, with studios grooming her as the next go-to female lead for big-budget comedies and dramas.
In 2009–2010 Heigl publicly criticized her own projects—calling *Grey’s* material “mean-spirited” and her *Knocked Up* character “sexist.” Industry insiders labeled her “difficult,” and offers evaporated. She was effectively blacklisted from major studio fare for years. The once-untouchable star watched her A-list status crumble because of a few candid interviews.
