Now, I could be wrong, but what I understand (have gleaned to this point) is that if a movie does not report box office returns, it becomes a "didn't release" movie. All actors are then untagged from the movie and it delists at zero. Again, I could be wrong, but I think you are correct as to the implication on the Starbond.
I know this doesn't help a great deal, but two suspicions is at least "damning circumstantial evidence"...right?
