I recommend that you don't use parent() on jQuery sets based on a class selector.
This selector fetches all elements that have the "moviename-big" class set, and then for each such element, their parent will be selected.... and than for each such parent, their parent will be selected ... and so on...
When you traverse the DOM tree, you normally want to make sure that you've got only one element selected....
For instance, inside a handler...
$(".moviename-big").click(function() {
name = $(this).parent()......
});
Also, instead of chaining parent methods, use the closest method...
$(this).closest(".box")......
