Hello zejae101,

After reviewing your post, it sounds like you purchased a movie, and need to download it to the computer. I would recommend that you read this article, it may be able to help the issue.

Download past purchases from iTunes - Apple Support

1. Sign in with the Apple ID that you used for the original purchase. Use these steps to see which Apple ID you used to download an item.
2. Check to see if the purchases you're looking for are hidden. If your purchases are hidden, you might not see them even after you follow the steps below. Learn how to unhide purchases.

Thanks for using Apple Support Communities.
Have a nice day
