I don't understand the question.
Are you talking about movies where the end credits include a list of the cast but don't include the name of the movie itself?
If so, my initial thought is that is probably quite common, but I'm not sure, because I've never really paid much attention.
I remember that Apocalypse Now was a bit unusual as far as credits were concerned. I think the end was just a blank screen, or maybe the title of the movie but no cast list or something.
