I've got a bit of a weird question, but I'm guessing you'll be one of the only ones to know the answer...
I'm wondering if it's possible that a movie and a movie collection can have the same ID or are they all unique?
For example, the Star Wars collection has an ID of 10, and no other movie has this ID, likewise there's a movie with an ID of 11, but no collection with that ID. That makes me guess that these ID's indeed are unique.
Is that correct?
