This study investigates the linguistic challenges of subtitling and coping solutions. Following the action research paradigm, this study first identifies the problem--- subtitling quality is poor in Taiwan and little research has been available that addresses the problem. Second, based on the analysis of the literature on subtitling and reflection on my own subtitling experience, it delineates the differences between subtitling and translation. Third, based on the characteristics of subtitling, it presents subtitling guidelines and a checklist. Finally, this study pinpoints the results and their implications for pedagogy. The analysis of this study shows that subtitling quality is poor in Taiwan not only because subtitling differs from translation but also because most subtitlers have not received formal training. Therefore, this study suggests that courses should be offered to introduce subtitling theories and practice systematically.
