What's the best way to load multiple movies using

the following method:

on (rollOver) {
_root.contents.loadMovie(“movie_name.swf”);
}

In the beginning, the way I do it for each movie is to place an empty movieclip at the top left corner, give it an instance name (contents) and then insert the name of the movie inside the (). But my current goal is different and a little bit more complex… When a user rollovers the button, it will display a collection of .swfs instead of one. A swf that contains the text, a swf that contains alot of sound clips, and a swf that contains alot of high resolution photographs tweening in and out. I don’t want to use one swf that loads up several movieclips designed for the functions I’ve mentioned. Does anyone know what’s the best way to accomplish this? At this point should I use variables? Thanks
