Deleting not synced items from iTunes

[Guacamole]

When I connect my iPhone to iTunes on my computer, on the left pane under Settings , on Films I have some films I don't want anymore, these are not on my phone but I get the option to sync them... but I want to completely delete these items but I have no option to do that.
Is there a way? Thanks

So you want to delete from everywhere? If so

Bring up the Apple TV app on your Mac. Right click, Delete from Library.
