The Weinsteins drop four classic Shaw Brothers titles this week and continue to fulfill their unspoken promise to release every martial-arts movie ever made. These DVDs span 15 years of the Shaws’ careers from 1967’s “One-Armed Swordsman” to 1981’s kung-fu comedy “My Young Auntie.” Below, watch an exclusive six-minute clip from “King Boxer” featuring Quentin Tarantino’s gushing commentary, and then see an interview with the legendary Gordon Liu from “The 36th Chamber of Shaolin.”
