No, unfortunately deleting the Movies folder will break the game; you should not delete it. Obviously, the installer was created a few years ago and since then, there have been a few patches that increased the total size. 32GB sounds about right.
You can try deleting some of the logs, they can be found in the "logs" folder, and there are some more logs under "swtor/retailclient/swtor/logs". However, those will only be a few MB in size. If you want to free up your disk space, you need to look for something else to delete.
