title: AS3: Apply Mask to Multiple MovieClips
body: <p>I have two MovieClips onscreen, and I want to apply the same mask to both. I set the the masks using </p>
  
  <pre><code>mc1.mask = mymask;
  mc2.mask = mymask;
  </code></pre>
  
  <p>Only mc2 receives the mask. How can I set the same mask for two different MovieClips without having to resort to putting them both in a single MovieClip?</p>
