Generally,
no, film schools do not require or heavily consider ACT scores. Unlike many undergraduate programs, film schools place significantly more weight on portfolios, writing samples, and auditions/interviews than standardized test scores. The focus is on demonstrating practical filmmaking skills and artistic potential.
While some schools *might* ask for ACT/SAT scores as part of a broader application, they are rarely a deciding factor in admission. A strong portfolio will almost always be far more important.
