The cast and crew of Warner Bros.’ King Arthur: Legend of the Sword ran a gauntlet of chainmail-wearing knights at the LA opening of the film this week.

Check out the 1000 Punches featurette below to get a glimpse of what that entailed, and then scroll through photos of the festivities at the TCL Chinese Theatre in Hollywood.
