Movieclip convert to a graphic

Question

hello every one
im trying to add to a movieclip called "movimiento"
a graphic  property
var movimiento: Graphics = faceRectContainer.graphics;
but the following error occurs:
/Users/ignacionieto/Documents/AS3/OpenCVFlash/Marilena_mod10/src/FaceDetector_Camera.as, Line 112    1119: Access of possibly undefined property x through a reference with static type flash.display:Graphics.
Is there a way to convert the movieclip to a graphic object, or other is there other alternative to control mc movimiento with the faceRectContainer variable?

If I comment
//var movimiento: Graphics = faceRectContainer.graphics;
It works well the bm image follow the g.rect object but goes static an the movieclip that consists in two frames appear only one : (.
Also the bm object doesnt dissapear i try to addchild to the g.rect the bm object;
g.addChild(movimiento);
g.addChild(bm);
but these error appear
/Users/ignacionieto/Documents/AS3/OpenCVFlash/Marilena_mod10/src/FaceDetector_Camera.as, Line 109    1061: Call to a possibly undefined method addChild through a reference with static type flash.display:Graphics.
How can I add the properties of the faceRectContainer to the m Movieclip movimiento so it could appear and dissapear like the g.Rect object?
Here oges the code
