Warning! There be spoilers here! Given the fact that many of the movies I discuss will be 30 years old or older, I think it's safe to assume that these podcasts will contain spoilers. If you haven't seen any of the movies discussed there's really only one thing I can say: WHY NOT???
Seriously though, if I do happen to do more recent films, say less than five years old, I will make sure that that individual episode has significant spoiler alertage on the podcast itself. If I happen to do a recent movie, that's still in theaters or VOD, then I will avoid spoilers altogether. Unless I don't, in which case there will be Spoiler Warnings galore. --Mark
