Idiomatic expressions are frequent in film dialogue, but their figurative meanings and cultural associations can create difficulties in audiovisual translation. This study aimed to identify the types of idiomatic expressions and the translation strategies used in the English-Indonesian subtitles of Enola Holmes (2020) ) movie on Netflix by employing a descriptive qualitative method. The current research also sought to find out the dominant strategy used in the movie. The data consisted of idiomatic expressions identified in the English subtitles and their Indonesian translations. The data collection was conducted by extracting corresponding subtitle pairs, and organizing them in an observation table. The data analysis was employed by identifying idiomatic expressions found in the movie subtitles, classifying the expressions using Seidl and McMordie’s (1988) typology, while translation strategies were analyzed using Baker’s (1992) framework. The analysis identified 142 idiomatic expressions. Seven types were found: Verbal Idioms (98; 69.0%), Phrasal Verb Idioms (23; 16.2%), Idioms with Nouns (9; 6.3%), Idioms with Prepositions (6; 4.2%), Idiomatic Pairs (2; 1.4%), Idioms with Adjectives (2; 1.4%), and Special Category Idioms (2; 1.4%). Two translation strategies were identified: Using Similar Meaning (83; 58.5%) and Translation by Paraphrase (59; 41.5%). The dominant strategies used in the movie subtitles was the Verbal Idioms which count for 69.0%, while the least used strategies were Idiomatic Pairs (1.4%), Idioms with Adjectives (1.4%), and Special Category Idioms (1.4%). The findings indicate that the translator prioritized semantic equivalence, naturalness, and readability while adapting idiomatic expressions to Indonesian subtitles. Further research is recommended to explore how cultural differences influence the translation of idiomatic expressions, particularly in maintaining their figurative meanings and cultural nuances in Indonesian subtitles.
