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)/Two of a Kind is a 1962 Hong Kong film. The film is notable for being Jackie Chan's film debut. The film is now considered a lost film, with no known complete film stock prints or the original camera negative remaining. The only footage that survived is a 9-minute opening clip and a short 5 minute clip of dialogue. On 5 December 2015 a 25-minute clip was released on the internet. Though a copy of the full movie was released onto YouTube on February 3, 2016, however this may not change its status as a partially lost film.
