We are very aware of the need for closed captions and are working hard to offer them as soon as possible. If an original film contains subtitles for non-English portions they are automatic in all movies.
Full movie subtitles or closed captions, however, are not a simple feature. Since our movies are completely customizable, depending on exactly which filters you choose, it is trickier to sort out full closed captions.
There are hundreds of thousands of variations of each of our movies, so it's not as simple as just having a closed caption overlay like other movie services. We have to figure out how to break it up across all those possible edits and still have it make sense, whether you skip one scene or 500 scenes. We are tackling it though, and hope to have it available in the very near future.
