One of the most exciting — and downright terrifying — films coming to Netflix this Fall [1] is Apostle, and now we finally have the first trailer. The occult horror-thriller stars Beauty and the Beast's Dan Stevens as Thomas Richardson, who returns home to London in 1905 only to discover that his sister has been captured by a cult led by the dangerously charismatic Prophet Malcolm (Michael Sheen) and is being held for ransom. Thomas sets out to rescue his sister, infiltrating the cult's brutal island community and eventually uncovering an evil secret. It doesn't come out until Oct. 12, so in the meantime, check out the trailer above and then stream all the other scary movies currently on Netflix [2].
