Before you go searching for audio described movies on your IOS device you need to turn this feature on under accessibility media settings. Then to search for audio described movies on iTunes you could get all such movies by going to the search tab and in the search field type AD or any one of the following Audio Description, Audio etc. The movies which have a audio description will have the image of audio description in the description of the movie. Check under the heading Languages to know in which language the audio description is available
