I agree that the picture of Bruce Li is incorrect. Bruce Li is the Japanese fighter dressed in black. He can be seen quite a bit in the first ten minutes of the film.
The picture identified as Chen I-Ho is also not correct. Chen I-Ho is not the cook (the cook is too old and does not have the mole); Chen I-Ho is a student and his big scene is around 33:35.
Removed Bruce Li and Chen I-Ho IDs (I'd got it in my head the student and the chef were the same person... will try to find an image with the student I can cull a portrait from).
