Big and Little Wong Tin Bar (Chinese: 大小黄天霸), also known as Seven Little Valiant Fighters (Chinese: 橫掃江南七霸天) and Two of a Kind, is a 1962 Hong Kong film. It is notable for being Jackie Chan's and Sammo Hung's film debut. Until 2016, the film was considered lost. The only footage that survived before that period were a 9-minute opening clip and a short 5-minute clip of dialogue. The film was rediscovered when a complete copy was released onto YouTube on 3 February 2016.
