All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ʻalayhi wa sallam, is His Slave and Messenger.
Contemporary scholars held different opinions regarding the status of acting in the Islamic law. The soundest view is perhaps that it is permissible on certain conditions. Ibn ʻUthaymeen was among those scholars who held that acting is permitted so long as it meets the following conditions:
"First, acting must be free of lies; if it involves lies, it is deemed impermissible.
Second, it must be free of playing the roles of those worthy of special respect such as Prophets, the Companions, Muslim leading scholars and the like.
Third, that it involves benefit such as addressing significant social issues or the like.
Fourth, a man must not play a woman’s role and vice versa.
Fifth, a human being must not play a role of an animal like the case when people play the role of cows or sheep, dogs, or the like for instance.
Sixth, a Muslim must not play a role of a non-Muslim like the case when a Muslim man plays the role of Abu Jahl, for example.”
The information provided in the question about your movie indicates that it is not free of the above violations. For instance, your movie would include people playing the role of devils or a sorcerer, which is impermissible, even if played by non-Muslims. Non-Muslims are required to observe the applied teachings of Islam as well according to the preponderant scholarly opinion in this regard; they are required to abide by the religious obligations and prohibitions that Muslims are required to observe and for which they will be held accountable. Please refer to Fatwa 85569.
Based on that, it is better for you to strive to seek another suitable and permissible alternative to accomplish your objective. You may film some relevant real-life incidents followed by the commentary of a reliable scholar and an exposition of its status in the Sharee'ah (Islamic law).
We implore Allaah to reward you generously for your keenness to clarify the truth for people and to combat divination, magic and superstitions.
Allaah Knows best.
