Mad Men's Jared Harris has joined the 3D action-adventure film Pompeii.

Directed by Paul W.S. Anderson, Pompeii is set in 79 A.D. and follows Milo (Game of Thrones' Kit Harington), a slave-turned-invincible gladiator who finds himself in a race against time to save his true love Flavia (Emily Browning), a wealthy merchant's daughter who unwillingly has been betrothed to a corrupt Roman general.

Harris, repped by CAA and U.K.'s United Agents, will play Lucretius, Flavia's father.
