VIDEO: It's Slash City in This Bloody Action Reel from Ironclad

Things have been a wee bit quiet where Jonathan English's 13th century siege pic Ironclad is concerned, but with the indie action pic's July release right around the corner Movieline's got just the uber-gory clip reel to set your pulse racing. (And, perhaps, your stomach turning.) Watch out, Paul Giamatti! The Knights Templar are coming for you.

Giamatti plays King John in the true story of a band of Knights Templar, led by James Purefoy, who resisted the king's siege of Rochester Castle in a historic 13th-century battle. Billed as "A Medieval Magnificent Seven," Ironclad co-stars Kate Mara, Brian Cox, Derek Jacobi, and Jason Flemyng.

The film is rated R "for strong graphic brutal battle sequences, and brief nudity."

Be warned: Nonstop sword-slashing, neck-slicing, blood-spraying violence ahead.

Ironclad hits U.S. theaters on July 8.
