Sorry, I don't have the exact names of the cast off - hand. However, they are probably actors with a wide range of skills. They need to be able to handle both the factual elements, perhaps acting as real - life people in some cases, and also the fictional elements where they might have to play more out - there characters. They would need to be able to switch between these two modes seamlessly to make the show engaging.
Unfortunately, I can't name the cast members right away. But thinking about what the show might be like, the cast could include both well - known actors and some new - comers. Well - known actors would bring in an audience who are fans of their work and trust them to deliver good performances. New - comers, on the other hand, might bring a fresh energy. The casting directors would likely look for actors who can convey a sense of mystery and intrigue, as that would be essential for a show like 'Beyond Belief: Fact or Fiction'.
