Need help with loading a swf file

I am a newbie in Flash.
Here is the problem.
I built a Flash movie. In that main flash movie, i want to load another small flash movie(movie.swf).
I used the code: loadMovie(“movie.swf”,target).
It worked fine. The only problem is that, the amination set out the small movie appears when i load it in the main flash movie.
The target and the movie( movie.swf) have the same size.
If i use a mask to hide any animation outside the movie(movie.swf), i have to make lot of changes. I have to make a mask for every graphic.
Is there an easy way to solve this problem? Please help me.
Thanks in advance.

Thanks jsk.
That is what i was looking for.
In my problem i loaded the swf file in the same level with the main movie. Thats why it went wrong. Thanks again.
