/**
 * movie objects may contain fields which contain "something" but are actually null:
 * e.g. response will read: "overview":null
 *
 * The presence of null means that get(key) won't actually return a null value.
 * Instead the get(key) method returns a JSONObject with the value of null. The toString() then
 * returns "null" string.//from   w  w w .ja  v a  2s.  co m
 *
 * This rather confusing API characteristic (if something is null.. maybe don't include it in the response?)
 * still allows us to:
 *
 * a. check for null
 * b. handle gracefully
 *
 * @param movieObj current JSONObject containing movie data
 * @param key key with which to retrieve a portion of the movie JSONObject
 * @return String value
