You can enable the hand cursor on a MovieClip by defining the following statement

MovieClip.buttonMode = true;

However the solution does not work in-case you have a dynamic textField in that movieclip. To enable hand in this case you have to additionally write the following statement

MovieClip.mouseChildren = false;

The reason is that the mouseChildren property determines whether or not the children of the object are mouse enabled. If an object is mouse enabled, a user can interact with it by using a mouse. The default is true which makes the dynamic textfield interactable and due to the textfield behaviour the flash player does not show the hand-cursor.
