Ancient Pompeii rises from the ashes, if only briefly -- spoiler alert: Mount Vesuvius erupts! -- in the new full-length trailer for Paul W.S. Anderson's historical action epic.

In the film, Game of Thrones star Kit Harington plays a slave turned gladiator in 79 AD who attempts to save his true love (Emily Browning) from marrying a corrupt senator (Kiefer Sutherland), even as the mighty volcano threatens to destroy the city.

Opening Feb. 21, Pompeii also stars Carrie-Ann Moss, Adewale Akinnuoye-Agbaje and Paz Vega.
