new netflicks download question

This past week Netflix has made it possible for you to down load i nHD a full movie to your smartphone or Ipad.,

my Iphone 5s had I believe about 3 GB available I downloaded a movie to test . .that made my available down to 2.4 GB .. whenever I went into my Netflix settings the icon had short cut to play ..

then I removed the movie within netflicks .. My iphone still reports 2.4 available and the movie is no longer available to playback ..

questions : Where is/was the movie stored and how to restore the iPhone storage back to 3GB ??
