Dynamically adding tween to n MC's - actionscript-3

Question

Here's what I'm aiming for. I'm querying the Rotten Tomatoes API for Upcoming Movies. For each movie returned, I'm creating an instance of MovieIcon (MC). I'm then adding this MC as a child of a Container MovieClip that's already on the scene. Each time, I'm incrementing the xPosition of each MovieIcon MC such that, they're positioned next to each other.
My container MC has a mask applied to it, therefore any child objects that are positioned beyond the size of the mask, they're are hidden from view.
How can I dynamically add a tween/easing animation between all these MovieIcon MC's so that when I hover over the Container MC, it 'scrolls' left or right, depending on the mouse motion?
Thanks in advance.

First I would recommend using a tweening library.
TweenLite and Tweener are good options
http://www.greensock.com/tweenlite/
http://code.google.com/p/tweener/
Both of these include docs that will help you get everything set up in your project.
Then you should be able to add a ROLL_OVER event to each of your MovieIcon MC's
MovieIcon.addEventListener(MouseEvent.ROLL_OVER, handleRollOver);
Inside your handler you can use the event.target property to get a handle on the over MovieIcon.
Assuming your using TweenLite you can go and add your tween to that target
private function handleRollOver(e:MouseEvent):void{
TweenLite.to(e.target, duration, {x: new x value, any other prop: any other val})
}
