Eli5: why do only some actors get the prefix “with” in a movie.

Question

I just finished Glass Onion and at the end credits it had all the actors who were in it but only Kate Hudson and Dave Batista had the prefix of “with” before their name. Is there a reason why only they get it?

Answer 1

When the Professor and Mary Ann were finally named individually in the Gilligan’s Island intro instead of being called “the rest” it was because of Bob Denver, who played Gilligan, demanding that if they were going to be “the rest” he wanted to be in the rest too. His contract said he could pick his billing, so the producers had to give in.
