Resizing an external movieclip?

so far i have this to summon the external movie

on (release) {
	loadMovie("trailer.swf", "placeholder");
	setProperty("placeholder", _y, "0");
	setProperty("placeholder", _x, "0");
}

as the movie is much bigger than the canvas itself i want to resize it. is this prossible? and if so, how. :slight_smile:
