As you need it in .NET. I already have it built for my Movie suggestion application. Movie data retrieving part collects movie data from IMDB. It uses Movie Name and Release Year to uniquely Identify a movie as there are many movies with same name but different release year. So if you put in a title you will get a list of movies if there is more than one with same title. It collects the following data at this moment
Name, Genre, Release Date, Description, Duration, IMDB URL, Casts, Writers, Directors, Producers and Languages
I have it ready and It might require little tweaking after discussing with you. So, I can actually deliver it in a day.
Please let me know if you are interested.
