ActionScript 3.0 :: Play Swf. On Mouse Roll Over?

I created a flash cs3 animation with about 6 layers.

I am going to place the .swf file into an html page I created with Dreamweaver. I want the swf file to only start playing when the user puts the mouse over it...and then stop when they take the mouse off. I know this needs to be done in the actionscript 3 in my flash document.

I thought it was something like this:

stop();
addEventListener(MouseEvent.MOUSE_OVER, playMovie);
function playMovie(event)
{
play();
}
