Dear B. Greetings from Islamicitys Imam. It is not allowed in Islam to act out the life of a prophet. The alternative is to do what Muslim scholars agreed upon to be an acceptable alternative, which is to have a background voice depicting the character of the prophet instead of seeing him. Judging this alternative from a purely artistic point of view, it can have a great impact if it is performed carefully and creatively. Few years ago, a movie called The Message followed this method and had a great impact. Good luck. Thank you for asking and God knows best.
