International superstar Jackie Chan explains how he designed part of his own armor in our exclusive preview for the action epic Dragon Blade, which arrives on Blu-ray and DVD December 22. The action star explains that, when performing complex fight scenes like the ones seen in Dragon Blade, carrying a massive shield will weigh you down in battle. To prevent this, Jackie Chan and director Daniel Lee (Black Mask) designed a much smaller shield that the actor actually wears as a wrist guard to block attacks.

Featuring an all-star cast led by Jackie Chan (Rush Hour), John Cusack (Love & Mercy) and Academy Award winner Adrien Brody (Best Actor, The Pianist, 2002), the worldwide box office phenomenon Dragon Blade will be available on Digital HD December 15 and Blu-ray (plus Digital HD) and DVD (plus Digital) December 22. The epic action-adventure is now available On Demand. From the director of Black Mask, this "visually stunning" (Asian Film Strike) film follows one man's quest to stop the Roman army and bring peace to his homeland.
