OED, OAAD, Webster's all say either form is considered correct. Language is a living thing. "Was" was correct before "were" was proscribed by the Latinizers. Now they're deemed equally correct.

It's now accepted widely enough that I generally recommend English learners should avoid the subjunctive entirely: people coming from languages like Spanish are much more likely to over-use it in jarring ways than under-use it, since the few remaining uses of it in English are not even used by many native speakers.

I think I would say "were" in this situation myself, though.

I thought that every time the title was mentioned in the body copy.

I would imagine that the choice of title and tense probably has something to do with the movie's plot and theme.

Yes, but I suppose it's that way on purpose. Bugs me too, though.

Unless I'm missing something, "Adam and me" looks correct everywhere he uses it.

Should it not be Adam and I?

It depends on the context. When combined with other subjective pronouns to form the subject of a verb, "I" is correct (as in "You and I are commenting on this topic"). However, when combined with other objective pronouns to form the object of a verb/preposition, you should use "me" (as in "Others are commenting on this topic along with you and me").[1]
