Double-check if there's a movie called "Tarzan X" but I'm more familiar with the 2016 one. Maybe they confused the title. If not, perhaps they're referring to a different version or a fan edit, but I should proceed under the assumption that they might be looking for the 2016 film.

Also, if they're into subtitles, maybe they're watching for educational purposes or learning Indonesian. I can mention using subtitles as a learning tool, but again, through legal means.

I need to remind them about legal and safe sources. Avoid providing direct links or methods that could be illegal. Emphasize copyright compliance. Maybe also mention that sometimes subtitles are added in certain regions, so checking their local service is best.

Wait, maybe they want the subtitles file for a different version, but I should make sure they know that downloading copyrighted material without permission is against the law. Encourage them to use officially available options.

Since they mentioned "substitel," maybe they're a viewer in Indonesia and want subtitles. I should suggest checking official platforms like Netflix, Amazon Prime, or Disney+ if the movie is available there with Indonesian subs. Also, recommend using the service's search feature for subtitles or contacting support for help.
