I struggle with the cultural obsession with spoilers and trying to make oneself into a knot of avoid discussing them. We all agree that it's just a bad move to spoil something when it just came out, but when does this become too much? A couple films which are known, perhaps infamous, for their spoilers are danced around as if they were released in the last couple of weeks like say
Gone Girl. If a film is good, then spoilers really shouldn't be an issue. A film ought to stand on the merits of the experience it provides. Films like
The Empire Strikes Back or
Seven don't need to necessarily be protected from being spoiled because they build up those cruicle moments so well that you will feel whatever the filmmaker intended.
However, cast lists can, and cannot, be spoilers. I have no doubt that Disney/Marvel cleared that Cap 3 scoop. That does not spoil a film where the marketing will heavily emphasize the conflict between Tony and Steve. Maybe if Robert Downey Jr's appearance were a small to medium sized cameo
I would be upset, but Disney/Marvel want you to know two avengers will be going at it and they want your butt in a seat on opening weekend. If they didn't, this would not have been posted by Variety.
