They have to extend the MovieClip class in order to be able to do that, am I
wrong?
I mean, If I load an swf with loadMovie (instead of creating an instance
with new) nothing assures me they are going to implement that class.
I'm a little lost in the relationship between movies and classes because I
always do composition, so I don't know how to load a movie and pass that
movie an interface.

Basically it really depends on what are they doing. Say you have a
player or main movie. You're tipically going to load different movies
or sections on it. And you want all sections to have a common list of
public properties and methods. Define that list and make it an
interface. Then, you can tell anyone: "do whatever you want BUT you
have to implement this interface"
If they compile against that interface you know that _at least_ some
properties and methods are going to be there for your calls. So within
your main movie you can do something like:
container.loadMovie("externalMovie");
[after fully load]
container.config()
container.start();
Of course if you have defined those methods in your interface. You
won't need to recompile anything.
Makes sense?
Cheers,
