Thanks.  I did have to cast it.  I had "private Clutter.Stage stage;" at
the top of my class and inside my constructor I had:

      var gtkstage = new GtkClutter.Embed();
      stage = gtkstage.get_stage();

And it gave me the error:

Assignment: Cannot convert from `Clutter.Actor' to `Clutter.Stage'
      stage = gtkstage.get_stage();
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
So I changed the line to:

stage = (Clutter.Stage)gtkstage.get_stage();

and it was much happier.

However I have a side question if you don't mind.  I have a simple
button that starts the animation, but anytime I roll over the button
during animation it slows down/pauses my animation, is it just my
computer or is there something special I need to know about?

Again thanks for the help.
