Abstract: A process for cellulose acylate film production which is sufficiently effective in reducing viscosity and in reducing moisture permeability. The cellulose acylate film does not suffer bleeding, i.e., the phenomenon in which a component separates out or volatilizes from the cellulose acylate film, has high flatness, is inhibited from having streak unevenness, and has high evenness. Even through long-term storage, the film does not suffer film deformation failures such as ridge failures or protrusion failures. This process for cellulose acylate film production comprises forming a cellulose acylate film by the melt casting method, and is characterized in that the cellulose acylate film contains at least one compound represented by the following general formula (1) and that the cellulose acylate film extruded from a casting dye in the film formation by melt casting is pressed between a touch roll having an elastically deformable surface and a cooling roll to produce the target film.
