Titled "The Awakening", the promo teases the resurrection of a deadly villain set on "destroying humanity", The Hollywood Reporter said.
Diesel plays the titular witch hunter Kaulder, an immortal warrior set the task of protecting New York City from a lethal plague.
Kaulder receives unlikely help in the form of a good witch (Rose Leslie of Game of Thrones fame), who can transport people between the real and dream world.
Ciara's cover of the Rolling Stones' classic "Paint It Black", recorded for the film, plays over the trailer as a bearded Diesel brandishes an impressive, flaming sword at his paranormal enemies.
"The Last Witch Hunter" will be released in the UK on October 21, 2015.
