To provide a cellulose acylate dope which hardly produces optical nonuniformity and nonuniformity in thermal expansion in a film-formed product, as well as to provide a cellulose acylate film.

The cellulose acylate dope has an exothermic peak of ≥1 J/g and ≤10 J/g between 0°C and 40°C. The cellulose acylate dope has an absorbance (A40) at 550 nm at 40°C higher by ≥0.02 and ≤3 as compared with the minimum absorbance (Am) at 550 nm of between 0°C and -40°C. The cellulose acylate film is a film made by using it.
