title: How can I read and write actor, director and producer data using Applescript?
body: <p>Is it possible to access actor, director and producer tags on a movie in iTunes using Applescript?</p>
  
  <p><strong>This returns empty strings</strong></p>
  
  <pre><code>tell application "iTunes"
      get artist of (track 1 of playlist "Movies")
      get composer of (track 1 of playlist "Movies")
  end tell
  </code></pre>
  
  <p><strong>This gives me an error (<em>A descriptor type mismatch occurred." number -10001 to item</em>)</strong></p>
  
  <pre><code>tell application "iTunes"
      get actors of (track 1 of playlist "Movies")
  end tell
  </code></pre>
  
  <p>If it's not possible using iTunes as the application, can I use Finder or something else as the application to access the properties I want?</p>
