Arena knows what it wants to accomplish and does so with professionalism, style and a fair amount of ingenuity. Although the film plays like Saw meets Gladiator, it also owes more than a little to films like Cube and Fortress. Twilight bruiser Kellan Lutz is David Lord, a rugby playing Denver fire fighter who loses his pregnant wife in a terrible car accident. Despondent and severely drunk he winds up in a Mexico bar with the intention of drinking himself to death. While flashing a wallet full of cash he attracts the attention of a corrupt bouncer who attempts a robbery in the bathroom. After making quick work of the hulking attacker, David is drugged and kidnapped only to awaken a prisoner and unwilling contestant in an underground fighting tournament.
