Starting a Movie clip in pause mode

Hi all

Hope someone can help? I've got a three-layer Flash movie made up with the following

layer 1 ::
the Movie clip itself.

layer 2 ::
the two buttons labelled "Start" and "Stop".

layer 3:: the actionscript which is as follows:

Start.onRelease = function(){
Movie.play();
}

Stop.onRelease = function(){
Movie.stop();
}


The buttons work perfectly when running it - but I'd like the Flash animation to start up in a static mode so that I have to click the "Start" button to get it moving. Any idea how I can do it?

cheers
