#9: Linda Blair as Regan MacNeil, The Exorcist
Linda Blair delivered a shockingly powerful performance as Regan, the young girl overtaken by a demonic force. Her transformation—from innocent child to horrifying vessel—became one of cinema’s most iconic images. The physical and emotional demands of the role pushed boundaries for child actors and helped solidify The Exorcist as a landmark horror film.

When she took on the role, Blair was an unknown teenager with only modeling and small acting credits. Suddenly thrust into an intense, effects-heavy production, she faced enormous pressure and public scrutiny. Despite the chaos surrounding the film, she handled the attention with maturity uncommon for her age.
