Is working as a chemist in film printing and developing laboratories for cinematic films permissible or forbidden?

The ruling on working in the preparation of solutions necessary for developing and printing films depends on the nature of these films. If they contain unlawful content, then the work is unlawful. If they do not contain unlawful content, then the work is permissible, based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Since the majority of these films typically contain unlawful content, it is advisable to leave this work and seek another permissible occupation.
