IMDB doesn't seem to have a direct API as of August 2016 yet but I saw many people writing scrapers and stuff above. Here is a more standard way to access movie data using box office buzz API. All responses in JSON format and 5000 queries per day on a free plan
List of things provided by the API
- Movie Credits
- Movie ID
- Movie Images
- Get movie by IMDB id
- Get latest movies list
- Get new releases
- Get movie release dates
- Get the list of translations available for a specific movie
- Get videos, trailers, and teasers for a movie
- Search for a movie by title
- Also supports TV shows, games and videos
