ok, it was a colour film in English. The main characters were a black man and a Chinese elderly man. The Chinese man teaches the man to fight by training him. there is a specific scene I remember where the black man has to hold a mouthful of water whilst he runs around the beach looking for the Chinese man. I watched this film when I was younger so I’m going to say 2000s. It was an older film though and I watched it on DVD. I for some reason think the word “tiger” or maybe “dragon” may have been in the title. I am not 100% sure though! Please help!
