            }
            if ($this->request->is(array('post', 'put'))) {
            $this->Movie->id = $id;
            if(!empty($this->request->data['Movie']['image']['name'])){

Since you are uploading a file, you must tell the Form handler to create the proper HTML. In your edit View, you should start with:

<?php echo $this->Form->create('Movie', array('type' => 'file'));?>

I think you did that in your Add view but forgot it here.

Hint: use the same code for both your Add and Edit view by putting the form generation code in a separate file, then include() that snippet of code.
