title: Get list of movies directed by director- IMDbPY
body: <p>I use the below code to get the director name of a particular movie. How can I get a list of all movies directed by the director.
  In this case I chose Interstellar and the Director I get will be Christopher Nolan. So how can I list all the movies directed by him?</p>
  
  <pre><code>from imdb import IMDb
  ia = IMDb()
  
  movie = ia.get_movie('0816692')
  print "Name of the movie: ", movie
  for i in movie['director']:
      print "Director: ", i
      for k in ia.search_person(str(i))[:1]:
          print k.personID
  </code></pre>
