I need to load a swf file and make a gotoAndPlay();

var urlReq:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.objLoader.load(urlReq);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,animationLoaded);

private function animationLoaded(event:Event):void{
var movie:MovieClip = event.currentTarget.loader.content;
movie.gotoAndPlay(3);
}

Does not work!!! need help!
